This matches our observations. The (few) problems we've seen have been 
services which advertise AAAAs but don't function correctly.

Handy hint: if you're running ISC bind as a nameserver and have a 
version with RPZ, you can selectively transform such AAAAs into NODATA 
responses for your clients, as a temporary workaround.
