Well we could just remove 'number-or-marker-p' 😃

Okay this is more difficult to fix... :/

I see your point, actually my main drive is to make the situation more
coherent so I'm unblocked in the first place, just the method
specializer functionality is a blocker for removing 'number-or-marker'.
I think adding 'number-or-marker' where missing is probably the best
solution for now.
Thanks
