chore: deprecate "fix CC slowness" feature

The bug has been fixed in the Community Console as per
https://support.google.com/s/community/forum/51488989/thread/269560789/message/277336217.

In the medium term we should remove the feature code from the codebase
once we're sure it won't be needed anymore.
