There is no other way afaik.

Only getxxxxinfo() functions are af-independent, so thre is no other choice.
btw. if servers share that connections database there can be problem
with ipv4-mapped addresses (the same connection will be represented
by 2 entries (one v6 on ipv6 ready ircu server and one ipv4 on ipv4-only
ready server)...
