Well I think that depends on how common use case is to have a dns
server per domain. Currently I think I can handle that in openconnect
directly, but if any other vpn application would like to do that,
they'll have to duplicate that code.

Interestingly it supports the 'servers-file' option which would allow
re-loading the domain specific servers without a restart. But even in
that case the cache will be cleared.
