I'm personally quite happy to have server registration.
My interest is in ensuring we have master-controlled robustness, which
is so far being ignored because "we need simple". Refrring to above, we
are clearly quite willing to go beyond the most basic implementation, so
there's no further argument to exclude it for that reason.
The implementation of master-controlled robustness is no more difficult
than the alternative.
