I would certainly also help.

To be honest, I don't think this will be a problem in practice. The amount of incremental change is small and there is already ongoing testing of all changes that go into the release (which should all be bug fixes). You may not get as much testing as for the primary release, but I suspect that many of those same people who test the base releases will also try the maintenance releases. Personally, yes, I'd contribute to testing the maintenance releases.
