Pass the register class or constraint or something like that to the hook, then based on what the hook returns, either or not do the reject? So your hook would special-case SCC_CONDITIONAL_REG, maybe a few more similar ones (those are confusing names btw, _REG but they are register classes).
It's a class of one register! Thanks Andrew
