@athal7 is there a reason you closed this? I'm really interested in seeing eslint-plugin-compat support in codeclimate

[athal7]

I can’t remember sorry @dkniffin

[dkniffin]

@athal7 would you mind re-opening it?

cc @larkinscott since you're assigned
cc @dantevvp and @noelia-lencina since you seem to be more active in here lately.

Also, I'd like to see this in previous versions of eslint. I'm currently using the eslint-5 channel

[athal7]

I’m not able to reopen, maybe worth starting a new one
