A new module that *is not enabled* would have to go through a lot of
efforts in order to break the build. Of course, if you enable it, you're
on your own, much like you're on your own with any experimental
module. The risk of breaking *the stable* PHP parts is negligible. Right
now, we knowingly ship PHP with large code portions which are not
stable. We consider this ok, because these modules are considered
experimental. Until this approach is changed, there's really no difference
between adding new experimental modules during the RC process, or before
it. That's why they're *modules*, and why PHP's modular.
Everything else you said is fine, except it doesn't really apply to the
issue at hand.
