I think the assumption is that only one plugin is capable of
implementing an extension. We only allowed to implement no extensions
at all. If you think we should allow multiple plugins to claim support
for the same extension, then it's an additional use case on top of
what we needed in qos. Why do you need it?

BTW feature/qos was merged in master yesterday, so it's now available
for all patches.
