FWIW, they have published metadata in InCommon (although it doesn't
look production metadata).

Presumably because their software doesn't support XML Encryption?
(Looks like they're using OpenAM.)

Well, the IdP only sends responses to trusted endpoints, so as long as
they maintain control of the endpoint, you're fine. XML Encryption
requires them to maintain control of the decryption key as well, which
Most federations (InCommon included) require every SP in metadata to
have an encryption certificate. Of course if the SP can't deal with
encryption, that leads to one-off hacks like this one. We've discussed
relaxing the encryption requirement in situations like this (but
haven't actually taken the plunge). The rationale is it's probably
better for such SPs to be in metadata even if they can't/won't support
encryption. It's a trade-off.
