Curious, if making salt effectively global, makes key generation less secure?

You're right, this actually doesn't actually add any security. Replaced to nil.
In our case we are going to pass the hashed, then signed denom as the privateBytes, so I think it should be good enough.
Added a comment to explain that the user is responsible for ensuring that the secret passed in (privateBytes) are salted or hashed beforehand.

This library is meant to be a general purpose cryptography library.
Currently we generate keys based on ecdsa private keys, and denoms, which are things that are specific to the use case of the CT Module we are building. However, those should not be the concerns of this library.
This allows the library to be used more flexibly without having a dependency on private keys and denoms.
