Somebody more familiar with the internals of region highlighting will
have to answer the last question.  I did not look at those internals,
but I believe that the region highlighting is just a display feature
and neither implemented a a text property nor as an overlay.  Text
properties are for longer lasting stuff.  If it were a text property,
activating the region  would mark the buffer modified.
