It's already possible to do

zle-line-pre-redraw() {
  whatever code
  other code
  z-sy-h-hook
  yet more code
}

Surely there has to be some limit to how lazy a user can be?

Also, if multiple things register for this automatically, it feels
pretty likely more than one of them will be trying to do highlighting
and then things will be wonky. And if you modify the buffer in one of
them like in the GP example, the order _definitely_ matters or you
will have highlights in the wrong place, so the user will have to
intervene in that case. If "plugins" are automatically registering
your more generic hook interface, it is very difficult for the user to
arrange for the order to be correct.

This has a weak NAK from me.
