Nice cleanups. My only feedback is on the commit messages, which are a
bit terse. Here's what I would recommend:

 - Explain what the commit does in the first sentence/paragraph of the
   commit message and then explain why/background info.

 - Include "No functional change intended." for commits that are
   expected to be no-ops. It's pretty obvious for most of these changes
   but it's still nice that have to convey your intent.

Commit messages aside:
