I wrote a patch to add point-left and point-entered to overlays. I ended up adding the implementation in command_loop_1. The patch is attached - let me know if anything needs to be fixed.
Thanks,

> By cursor motion, do you mean such as the cursor_to function in terminal.c?No, not exactly. I mean more generally to trigger the code based on the
motion that happen from command to command. It could mean a hook in
something like cursor_to, but it could also mean a hook in
command_loop_1 (along the lines of what's done with
adjust_point_for_property.

for operations that do a lot of internal movement.
E.g. diff-context->unified. Point-motion hooks will be triggered many
times during a run of diff-context->unified (and may accidentally cause
it to fail) whereas cursor motion hooks should only be triggered once
after the command is done, so it can't cause it to fail.
If such a hook is run a bit more often than strictly needed, it's

usually not considered a bug (tho it is recognized as a misfeature).
So it might still be acceptable.
