On one hand, they aren't special casing their own products, so good on them I guess? On the other hand, if they can't detect this, what point is their spam filtering even?
Public mail services can be surprisingly bad at what they decide not to catch. I love Fastmail but because some existing customers rely on it, the default behavior is not to block inbound emails with the same domain as you've delegated entirely to Fastmail.
One would expect a given provider should, unless instructed explicitly otherwise, block outside emails from domains it controls mail for.

It's not even something you need to specifically craft much infrastructure for. There are public standards for "don't accept email from this domain unless the sender has a cert encrypted by one of these CAs" (Google runs their own CA, yes?) and "don't accept email from this domain except from these servers" and so on.
