Comment (by jb510):

 Maybe already added to the conversation. But most major services (FB,
 TWTR, do already support WebP for open graphs tags, even if not officially
 in the spec yet.

 This link has a nice recent compatibility chart for reference:
 https://www.ctrl.blog/entry/webp-ogp.html

 Perhaps instead of accommodating those outliers, WordPress should be
 pushing them to catch up with the others.

 Regarding multi-mime.  All this seems to be hamstrung by the face that
 these are all being generated upon upload, rather than on first use.

 I really feel before we accept the storage and performance impacts this
 would cause that some serious consideration needs to be given to
 approaches that would modernize thumbnail generation and the needless
 preemptive generation of so many thumbnails:
 1. Simply store the original in whatever format it's uploaded
 2. Upon first request of an image, serve whatever is closest and then
 attempt to generate the correct size and format for next time.

 Timthumb did this 15 years ago, surely we can do better today?
