Yes, these are the problems or dangers.

Hmmm, I don't agree completly. The core sitemap syntax has to be carved in
stone. True.
*if* we would use a different namespace for the plugins, like the flow,
than the sitemap can still be validated without any problems. The
application will of course not run, if your sitemap uses the flow, when
the flow is not available. But the same happens, if the fop serializer
is used and is not available.
I agree with you, if we give the plugins the same namespace as the sitemap
