LGTM.

Sorry about the delay.  I ran some tests, and it looks like this doesn't cause any regressions.  Granted, it didn't lead to any performance improvement either (I guess we don't really use this information in many cases).  But having the information around could be helpful in the future.

Do you have commit access?
