Comment (by swissspidy):

 > Also, why minor and not major versions? The policy doesn't say anything
 about this.

 FWIW I don't think Safari really treats those as minor versions, they
 don't follow semver.

 > In my opinion, for the frontend, it would be better to use global usage.
 Something like global > 95%. For the admin is a different story.

 Just noting that this browserslist config and browser support policy page
 have been like this for years, ever since Gutenberg got introduced. My
 proposal is based on this existing documentation.

 If we want to change the WP browser support policy I suggest writing a
 detailed make/core proposal, including a draft PR for the browserslist
 config so we can vet bundle size differences.
