WebP never got much traction, and makes zero sense to push for it now, as the dramatically better AVIF already exists.
however AVIF only has about 65% market penetration.
If you ran a serious webserver, it would make more sense to do automatic on the fly conversion using mod_pagespeed. This way it handles browser support for you.
Seriously, people, stop transcoding to "newer, better" formats at lower quality. Just stop. I should never have a better experience if I set up an older browser that doesn't accept your newfangled stuff. Either manage to get the quality right (easier said than done) or just don't transcode stuff.
(This is much easier to get right if you are also shrinking an image.)
