Yes, I think that's the only solution currently for disabled queues, but
I'd guess it's straightforward to avoid them as an option if someone
would like to try. We don't currently use AR, so I haven't looked at

I tag bad nodes with a comment and put them into a "testing" hostgroup
with access only for admins (via RQS, which will be ignored for AR for a
reason I don't follow). I think if node user_lists were used instead of
the RQS to restrict access, an AR would exclude the bad nodes for
non-admins, but I'm not sure.
