Yes, it does.

They are not very efficient, true.  I should have written down why I
preferred them over text properties, but I think it had to do with the
fact that changing overlays does not count as a buffer modification,
but changing text properties does.

If the python-mode situation is any guide, GNU Emacs integration is a
bad idea because it will eventually lead to fragmentation.
