Less useful, as it requires a reboot with a borked init. (Safe reboots
are handled by init, remember.) So, you're talking about adding borked
filesystems to the borkage of init and su. "exec login" has none of
these disadvantages.

Technically, there are very few "musts" in computers. You can change
nearly anything you want, given enough time and resources. So, it's all
about tradeoffs.
I suppose I'm just prepared to give the Hurd team the benefit of the
doubt for now.

That is, assuming you can log in when you get home. :-)
