Comment (by adamsilverstein):

 > There are still entire industries (insurance, government, non-profit,
 medical, etc.) requiring Internet Explorer compatibility.

 Good point @blobfolio - and although we are planning to drop IE11 support
 in WordPress 5.8 it is important to consider these cases.


 > Whatever approach ends up being taken, it is important to allow sites to
 opt-out of any fallback/compatibility-testing functionality (in addition
 to being able to opt out of conversion).

 Absolutely, we will provide a way to opt out of the shim as well as the
 mapping to a new format. In addition to code level filters **I plan to
 provide a plugin that will disable the shim/mapping**.



 > Global usage stats are a good place to start, but don't really mean much
 when it comes to predicting the kinds of traffic any individual site might
 receive.

 Right! that is why sites can opt out - while the vast majority of sites -
 and users - still benefit. In the case of WebP, we are fortunate to both
 broad browser support **and** a solid shim.
