That's true, but it seems like an unnecessary complication.

For instance, the mode line contains `minor-mode-alist', and has to loop
through it to find the lighters to display.  It could instead work off
of the `minor-mode' list, which is order(s) of magnitude shorter for most
people.

(And whatever mechanism we add for global modes.  Just adding a
`global-minor-modes' variable is the obvious solution, but I was hoping
somebody had a non-obvious alternative.)
