Well, it is somewhat similar to the behaviour of the load balancers for
mail.protection.outlook.com, which return NOTIMP for even more RRtypes,
e.g. TLSA:

    _25._tcp.nist-gov.mail.protection.outlook.com. IN A ? ; NXDomain
    _25._tcp.nist-gov.mail.protection.outlook.com. IN TLSA ? ; NotImp

I doubt that's the intention, but perhaps it points to a common origin
for the underlying DNS load-balancer platforms?  If so, with a bit of
luck software/firmware updates may be available to address both.

It is otherwise an interesting coincidence that both Google and
Microsoft ended up pretty much the same bug.
