Unrecord will work as often as you need it to, and it doesn't stop working
at tags, since tags are just another patch.

I think you've got a mistaken view of darcs and how it's supposed to work. 
Unrecord (and it's more violent cousin unpull) *can* lose data, but it's by
design, not by accident.  I can use 'rm' to cause data loss too, but I'm yet
to see anyone seriously advocate for the removal of rm from Unix.

I think it would be a terrible thing if unrecord was removed.

It might help your understanding if you think of darcs as being a little
more like multiplayer quilt than some sort of mercurial clone with different
commands.  Darcs is (thankfully) like no other revision control system out
there, and it can definitely take some getting used to.  Making sweeping
statements about it's design before you understand what it's trying to
achieve probably won't endear you to anyone, though.
