"R is for right, L is for left, U is for Up, etc. And when you need to turn the middle layer, it's N. I don't know why N but it cannot be M because we used it wrongly previously".
Not very different from "D is for down because B is taken for Back", and we just had to pick something.
We're very used to U for Up, but I think "T for Top" is more natural if we don't worry about D. (Also, T is a consonant. Using consonants for outer moves would be very nice for mnemonics.)
I think we should just replace M' with M and vise versa. Imo it's worth a little confusion for year or two to get things right for the long run.
No, no, no, no, no.
Using N for M' might cause confusion.
Switching M and M' would cause completely unresolvable ambiguity.
We had enough of this problem with lowercase moves because of the old WCA notation, and I'm glad we just barely go that over with.
