It is a cost of an extra if, I tried to avoid it. I like it better with > these two hooks, but if you have a strong opinion I'll do it, just confirm it again. The cost of an indirect call is actually higher than an extra if/else block. I'm not against paying this extra cost when implementations are completely different, but that does not seem to be the case here. Moreover, if you get rid of these hooks, you can also get rid of the cfg struct.
