Second, at first I liked the idea of disabling unstable blocks by default, but after looking at blocks.properties I get the feeling that all that would do is make it a pain to get the sample site working, unless the build was changed to use a samples.blocks.properties to build the sample site. Blocks.properties clearly identifies the unstable blocks so I don't think that is a problem.
Except that practically no one is reading it: have a look at INSTALL.txt, most people will read just the first section, and there is no mention whatsoever of unstable stuff.
