Anything blocking this from getting merged?

Only a review from @ljharb

[ljharb]

also, the word "chore" is very inaccurate; chores are burdensome and changes like this are helpful.

[gajus]

@ljharb Did you want the commit to be renamed to feat:?

[ljharb]

nah, conventional commits are garbage :-) i just haven't gotten back to it since the last update.

[ljharb]

I think because the parser added an engines declaration in v7.11 that drops node 11, npm selects eslint 6 to match, and then that fails the peer dep requirement. Let's see if this does it.

[ljharb]

k, turns out all versions of babel's eslint parser have a peer dep on eslint 7, which has an engines that doesn't include node 11, so that's the issue here. alternatively we could stop testing eslint 7 on node 11, which i'll probably just do in a followup commit.
