This is an issue that has a number of different camps, different ideological points of view. For example, frequency separation removes a LOT of very small details, and that tends to make
real people look very obviously retouched/processed/artificially enhanced. If the subject is obviously young, obviously has been heavily perfected in the makeup chair, or is part of an obvious "concept image", advertising image, or some purpose-shot image, then a lot of skin editing might dovetail perfectly into that, and might be just what is needed.
But what if the image is supposed to look real, and convincing, what if it is supposed to look "authentic"? What if the image is supposed to look "genuine"? Removing too much detail can make the image look the wrong way, look doctored, look hackneyed.
There is a huge reliance on frequency separation these days. I'm not a fan of it for my images. I prefer a more real look, where lighting is used more to keep fine detail from showing up to the extent that removing said fine detail is not very necessary most of the time. For example...if you use a main light and then a fairly strong fill light directly opposite, it keeps the actual level of micro-contrast fairly low...for example, if you "stack" or do a side-by-side with two light sources of approximately equal strength, that keeps shadows from forming, so skin looks smooth, right out of the camera, and you might actually end up painting on some more contrast with a brush!
I dunno...I think one of the most important things to do is to clone out major skin flaws, like blackheads, pore clusters, things like that, but to LEAVE IN the major facial characteristics that define "real people". For fine art/modeling/glam stuff, you can retouch and refine more of that suits your shot or your idea of what looks best.
Skin editing can be, for some people, a major ideological issue...this is an area where opinions often run strong. There are a LOT of people today who smooth the chit out of every image. Their work typically looks ridiculous to my eye. Just because one can, does not mean one should. But yes, there definitely ARE trends in how images are retouched/processed/refined, and they do tend to come in and out of fashion. Remember
the Dragan Effect....remember how popular and how widespread that was, that effin' ridiculous look? it was allllllllll over the web and in print six or seven years ago, but it has faded in popularity because it so often looked hackneyed.

Years ago, Gaussian blur was used as a way to smooth images...fast, easy, kind of pretty--at times...but also rather blase after we'd seen ten million images done that way every year... Same thing with reduced clarity....when the Clarity Slider was first introduced, that was often used...and if done well, can be pretty neat...but it can be over-used.
We're starting to see a lot of images where simply put, there has been wayyyyyy to much smoothing done on photos for which that technique is counter-productive... A lot of people are more interested in the retouching and Photoshopping process than they are on the photography/lighting process, and at times these folks are churning out images that look, well, clownish is the word that comes to mind.
I look at it this way: skin editing is like salt and seasoning when cooking. You probably do need to use "some", rather than "none". But not too much so that it spoils the dish. But enough that it tastes right!
The problem, as I see it, is the tendency for people to hammer-and-nail images in an unthoughtful way, where every problem looks like a nail to a guy who only has a hammer. This stems I think from people learning a method, from a web-based tutorial, and then applying the same basic routine, over and over, no matter what. And that is, I think, why these fads come and go...something becomes popular, and people accept it as normal, and then after a time, something else comes into fashion, and
the sheeple decide, "
Hey! I want to do my photos that way too!" Images are now often seen among many similar images on 500px, Flickr, and so on, and many people have a herd mentality.
