Upgrading to v4 - Cannot namespace Page and PageController

[WillGibson]

I'm just starting to experiment with upgrading to version 4 so we can see how close it all seems to being practical to do on our clients' sites.

I namespaced our Page and PageController classes during the upgrade, and this blew it up.

I've un-namespaced them for now, but was wondering if there is a plan to make them namespaceable, or whether the global namespace is still the preferred situation here?

Perhaps at ss 5.0 we won't have Page at all, and have a better composability solution for SiteTree along with content blocks and extensions.
