7408d87465
It was added in 7340485014
but for some reason never enabled.
This was supposed to be protecting us from performance regressions
by monitoring the size of modules in the repo. It appears to be
broken both locally and on Jenkins when run on the due to some changes
in Phabricator.
Since then we've added bundle size tests to Vector using a different
more foolproof method. I think that method is more preferable as it
also provides coverage for JS and icons so the
associated script is copied over and used in Minerva
and activated on all commits.
