Comment (by justlevine):

 @johnbillion @SergeyBiryukov I opened up
 https://core.trac.wordpress.org/ticket/63268 so I could have a place to
 tag my incoming PRs. Somebody with more perms will need to triage/label it
 correctly.

 Regarding the existing open PRs attached, can we get them reviewed before
 closing this ticket or should I reattach them to #63268 (and if so, is
 that as simple as updating the PR description, or is there something else
 I need to do)?

 List for easy ref:
