This assumes you can control the server key/cert you want to trust.

Hm, why would trusting an EE certificate invalidate the name checking?
I can see it only disable the CA chain checking.

This sounds like it has lots of potential for people to accidentally
do that and don’t realise it. It also prohibits mixed setups (think,
almost-normal operation, you have a (possibly reduced) set of CAs you
want to trust, plus one or a couple of EE certificates, which are
special cases.
