Agreed.

I think the correct thing to do is too costly for an operation that's
performed every time we move point.
The right thing to do is to declare point-entered and point-left
properties as obsolete and replace them by something like cursor-entered
and cursor-left properties which are only checked at command boundaries
(or better, checked just before redisplay).
