Indeed, and it changed further in 22.2.

I'm not sure I understand.  Are you saying that you don't want comments
to be aligned in that case?

If you need more control over the placement, rather than a variable
comment-indent-fixed, maybe we should just say that if
comment-indent-function returns a list of a single integer, it should be
taken as the indentation position and not second-guessed.  Or it could
return a cons cell (MIN . MAX) to say "anywhere between MIN and MAX".
