RFC: expire all reviews older than Sept. 1st from Phabricator

[Augie Fackler]

Howdy folks,

I think I'd like to expire all reviews from Phabricator that haven't been updated since September 1st of this year. That's a lot of reviews, but they all seem pretty dormant at this point. Obviously people can reopen them or start new ones as appropriate. My methodology would (probably) be to write a script to do hijack&abandon all the reviews that matched the "not modified since Sept. 1st" constraint.

Thoughts? Should I go for it?

Thanks,
Augie
