This is a very convenient thing, and it makes it easy for neophytes to
understand a one-liner on how to get off the stinkin' list:
"to unzubscribe: send a message to foo-freaks-remove@wherever.org"

I've used lists like this. The only bad feelings I have is remembering
what method to use. This shouldn't be a stopper.

Do we? Why not write it such that any command could have it's own
address. Write mj_command to read it's command line as a format string,
and treat the result as a command.
foo-freaks-remove: | mj_command unzubscribe foo-freaks %F
lists-which: | mj_command which %F
lists-command: | mj_command %S
Where mj_command replaces %F with the contents of the From: header, %S
with Subject:, %x with X-MajorDomo, etc., and then executes the command.
I have no initial clue what interpolations other than From: might be
useful.
If this is too complicated (too clever by half, I believe, is the phrase),
then just a dedicated unzub address per list would be helpful and anything
else is gravy.

They don't have to. Only the "basic" MJ command method works on those
sites.

Yes and no. All methods that worked on 1.94 still should work on 2.0.
There are now just new options available in addition.

True, but tokens are pretty cheap. Parsing and generating errors for the
spam sent to the majordomo address is probably a whole lot worse.
