I think it's related to the overall popularity of RPGs nowadays, when maybe 10+ years ago, WRPGs were still a bit niche or more catered to enthusiasts. This changed with Bethesda and BioWare games, now there's a huge mainstream audience for RPGs. So before, something like Gothic 2 or Morrowind would come out and while the combat was janky, it was mostly about the RPG features. The jank was pretty much accepted by players, because of course the RPG parts of the game were the focus.
Now, players expect not only the cutting edge RPG features, presentation, design and overall depth and length, they will not overlook any jank or awkward game control for the combat. BioWare, CDPR, Bethesda et al now have to chase the perfect game. Mass Effect Andromeda is a good example of how difficult it is to get right. The first Mass Effect game had relatively poor combat game control, but is still lauded for all of the RPG elements it got right and innovated on. It's been a struggle for BioWare to focus on not only all of the RPG features but make it a good action game as well. Nintendo doesn't have to worry about which character can be romanced or how they handle interspecies sex when they make an actual ARPG.
