Differential endpoint settings in authorization.bxb for dev|prod

I'd like to be able to set up authorization.bxb so that all values in it (but particularly token-endpoint and authorize-endpoint) can be different between development and production.

For example, I want the token-endpoint to call https://my.dev.server/token_url during development and call https://my.prod.server/token_url in production.

This could be achieved similarly to the way "client-secret-key" does it, or it could be done by permitting dynamic population of the values from the config/secrets or it could be done by having different authorization.bxb files for dev and production. Or possibly several other ways too :).
