Yes, it does. Point buffering should work also.

Right. It should work that way.

Well if the hole is covered by the 'buffer' are it's going to disappear in the result. What do You mean 'considered'?
> are negative buffer sizes supported?
Yes. The area of a resulting polygon will be smaller and holes respectively bigger.
