I think that Jeff's impressive textconv caching is only the first of
many uses of notes where the notes ref is not a branch head with
continuously added history, but where the ref is being rewritten over
and over again. Also, people may rewrite their refs/notes/commits when
experimenting with remote notes trees.

In both cases, I deem the reflog "backup" a useful safety measure (just
as for other refs), and the automatic purging of the reflog provides
just the appropriate housekeeping.
