Yes, that's a nice idea. We have quite a number of 'conditional
callbacks' in various critical paths that could be made lighter via such

It would also free new callbacks from the 'it increases overhead even if
unused' criticism and made it easier to add them.

We can take the "immediate values" infrastructure as a first step. Has that been merged?
