Certainly true.

yes, what's more maybe we could do away with major *numbers* completely
and use major *names* instead.  16 bits would be enough space for a
2 character name (which the whole universe, almost, could just treat
as a number).  Given this, all the absurd renumbering of all the entries
in /dev every time someone rearranges [cb]devsw could be done away with
once and for all.  (Yes, I know that 2 chars isn't great, but it does fit).

Imagine ...
