Unnecessary dependencies for a custom primary key

[cblp]

I want to work with a database outside of a web server.

When I define a custom Id or Primary, Persistent requires me to define instances PathPiece, From/ToHttpApiData, From/ToJSON, but I don't need them, it's extra code and extra dependencies for the project.

Could we disconnect Persistent from the web server usage?

That is unfortunate. I agree that'd be nicer. At least some of those are required in the superclass constraints of PersistEntity and removing them may be a breaking change. Some of the other ones are in the instance derivations for Key - those we can probably just make conditional.
