[Unbound-users] Filter AAAA records in unbound

Greetings to all,

I am a newcomer to unbound. We will evaluate unbound as an alternative
to BIND for a new anycasted caching resolver setup. 
One thing we will need in practice (and many others might need as well)
is the possibility to remove all AAAA records in replies for various
IPv6 brokeness cases in our networks. BIND provides the feature
filter-aaaa-on-v4 in recent versions (post 9.7) if compiled
accordingly. I can understand that this should not be considered a
permanent solution to the brokeness issues, just a quick workaround
(hopefully with a short life-span).

In the bug case

which seems close but not quite the filter-aaaa-on-v4 BIND
functionality, the STATUS is marked RESOLVED LATER.
What do the developers think about introducing a filter-aaaa feature,
similar to BIND's, especially with the v6 launch day approaching?
