Ah, no.

Probably the best thing to do is require the federation plugin to always 
be installed, and in the non-federated environments declare your 
upstream_set(s) empty. This does require a bit of configuration on the 
non-federated environments though. I'll have a think about whether this 
can be improved.

Thanks.
