The kernel, even its bugs, should be stable (in that they shouldn't change unless it happens the correct way). If not, it starts introducing unexpected issues to users.

If someone's testing against these versions, adding their fixes and patches, stuff like this will break things for users. He can't assume all users will be regular desktop users, even on an experimental area of the code.

Things like 'RC' have meaning. Meaning that has been there for years. He can develop on a separate tree and users that want it can use it. This is used all over.
