Can I do each of these in turn, preserving metadata in the commits, but then submitting one mega-backport PR for them?

[Trott]

#10479 should probably happen as well and first. I'll include it in my mega-PR (if it's OK to mega-PR this).

[Trott]

#14417 is a no-op when applied to v6.x-staging, so it can be left out.

This also needs the ESLint updates for bug fixes.

Will need nodejs/node#13950 too.

All backported in nodejs/node#14835
