When writing unit tests, I'd like to be able to unregister a component, so that I can test various scenarios of the registration process. The spec doesn't deal at all with removal of custom elements.

I'm writing code that actually performs element registration depending on backbone configurations, if that helps with context.

I think the solution is in being able to create/discard registries. See bug 24578.

Would using separate iframes be enough for testing?

Yes, existing test frameworks use iframes.

I'll close this as the real solution is #154 but in the meantime iframes suffice.
