That is the problem. There are cases of IPv6 brokeness today inside ISP 
networks that will be exposed when AAAA records are published in large
content providers. Although not the proper solution, until the problems
are identified and fixed properly, there is a need for a quick
workaround. Filtering AAAA records is such a weapon in operator's
hands.

OK understood. Time will tell if this is a necessary option or not. If
it is, I guess people have at least BIND and its filter-aaaa on v4
option.

Kind regards,
