Well I'm at least assuming that we wont have this case anymore, i.e.
there's only two kinds of parameters:
- those which are valid only on proto context
- those which are valid on both (like priority)

This SSEU thing looks like a 3rd parameter, which is only valid on
finalized context. That feels all kinds of wrong. Will it stay? If yes
*ugh* and why?
