Would it help if define-minor-mode recorded what the
variable/expression is (e.g., by putting a property on the function
symbol)?
This could also be useful for define-globalized-minor-mode (see
Bug#29081 - for which the current suggestion is to do without that,
but if such a thing has two uses, it will likely be helpful in even
more situations).
