It's up to you.  If I were you I'd ask the user to re-exec hl-line-mode
for a new value of hl-line-sticky to take effect.

Probably "instead".  But here again it's up to you.

I think the global mode should be implemented directly, using the global
part of post/pre-command-hook.  But guess what.... it's up to you ;-)
