Correct, DDNS stops working.

No. And in general, you can't anyway (that's not a DHCP limitation,
it's a limitation of at least one of the major DNS implementations,
and I assume others). It is a definite possibility to create a
database system that allows updates to a slave when the master is
down - but you've only to look at the way failover works in DHCP to
see how quickly the complications build up when you take all the
corner cases into consideration. Not least of these complications is
how to merge two sets of updates - considering it's possible to have
mutually incompatible updates to apply.
