LGTM

same as per comment from #1509:

opened a new issue related to stable release policy (#1549).
appreciate the work @faddat but these changes don't make sense to merge into those versions unless they're going to be part of a new release of those versions and EOL should only be bypassed by security updates.

Except that legibility & standardization is a security update.
