I don't have a strong opinion, but it seems like if a variable is 
modified by explicit command from the user, major-mode-remap-alist seems 
more appropriate than major-mode-remap-defaults (which would be about 
some global defaults).

Not 100% sure though - because that plan would delete the vast majority 
of the uses of the latter from the core (except for TeX's mappings, it 
seems).
