No, "EC" isn't an alias for a particular curve.

Are you concerned about duplicate checks?

I'm confused by this comment. With removing the hardcoded aliases in
AbstractAlgorithmConstraints, which is what I thought you had suggested, EdDSA
and Ed25519 are now separate as the check is effectively a string compare check
against the disabledAlgorithm list
The second half of that case statement has a key that can check against both
EdDSA and the NPS.
With respect to `CryptoPrimitive.SIGNATURE`, it just a value used in the test,
it can't be null.
