A minor mode is certainly incorrect if it doesn't work as intended when
`parse-sexp-lookup-properties' is t.  A minor is also incorrect if it
globally sets `parse-sexp-lookup-properties'.  Hence, as you note, only
the behavior when killing this variable locally matters.  If modes need
conflicting values for one and the same variable, they must use a `let'
binding.

It would require a minor mode to add a symbol to a list when it is
turned on and remove that symbol when it is turned off.  I don't think
that's a lot of work.
