I don't object to that, either.  The question is: what we will require
the Git log messages to contain then?  Currently, the entire ChangeLog
entry goes there, but once the manually written ChangeLog files are
retired, what will remain?  That was the crux of the recent
discussion.

Well, I personally will lament the loss of that information.  It's up
toy you-all to decide how much does that weigh.
