I'm in favor to get this merged ASAP, yes. I think distribution
maintainers should backport it to versions from v6.3.4 to v6.7.0-rc2
(the upcoming v6.7.0-rc3 should include the patches).

I guess this might be confusing or make bad things (including data loss)
if applied on mails that has moved from a folder to another one without
a full filename change because this might lead to UID conflicts.
