 > I think your concerns about storage are exaggerated.

 With all due respect, I'm not exaggerating one bit.  I'm basing these
 concerns on having worked through image optimization (via Shortpixel and
 Imagify) on literally hundreds of sites.  Sites with anywhere from 3,000
 to 40,000+ images in the library. Often there are hundreds of thousands of
 thumbnail files, and, in some cases, the numbers reach into the millions.

 As I've mentioned before, on a near-daily basis we have clients running
 out of disk space on their hosts because of thumbnails.  In our situation,
 it's often the backups from Shortpixel or Imagify... and that roughly
 tracks with the same amount of disk space that we're talking about with
 the WebP Conversion (should all the thumbs be duplicated). The savings is
 roughly 30-50%, depending on the original images, but these plugins keep
 the originals so, overall, the uploads folder's disk space usage can grow
 by 30-50% or more.

 These aren't "extreme" outliers -- they are simply active, reasonably
 successful blogs (most are food/recipe blogs, but we work with a variety
 of other publishers and e-commerce sites).

 Moreover,
 [https://docs.google.com/document/d/1_si5UPkjC9R5yPPL6FPWfx7jahB8GPb2lrxGpdigYDM/edit
 your own research indicated that up to 14% of sites] could run into
 hosting space issues!

 So no, I don't think I'm exaggerating or overreacting here. You're
 proposing something that will absolutely cause issues on a significant
 percentage of sites over time -- possibly up to 14%, far far above the
 threshold that should be considered acceptable.
