"Revision history would still show"

Except in a distributed system like Twitter (including client and server) there is no single timeline, and amateur digital forensics will erroneously say "aha, but you retweeted it before it was edited"

As long as RTs and likes are tied to a specific version of the Tweet then it's no real problem.

Perhaps, but you are talking about creating rather complex machinery in order to support a tiny feature. If the only argument in favor is engagement statistics (would those take edits into consideration as well?), I certainly see why Twitter doesn't care too much.
