So, unicast sites never go pear-shaped? That's new to me ;)

Statistically a properly maintained anycasted IP service provide better
reliability than unicast. Most anycast constructs are also made to
improve performance. Thus, adding unicast-servers as you suggested
earlier may cause performance-degredation for those request that go to
the unicast destination. Given that you can't prioritise one NS instance
over another, does it really make sense to add unicast hosts if you
already have multiple anycasted hosts?
