Oh, sorry for this, but these ideas have been ringing in my head for quite some time...
I have also others, all in the direction of further improving Syncope, and I am happy to discuss
here to clarify, better define, go beyond my direct experience, etc.

Interesting point, indeed.
I admit that below I was exactly referring to Syncope's External Resources, but your sample
about REST service is significant.

Let's suppose we introduce the new concept of Application: what kind of communication will
Syncope establish with it?
Coming to your sample: what would be the use case of managing in Syncope the privileges available
into an external REST service? How would you fetch them? Supposing you're able to associate
them to (groups of) users, wow would you push such association to the REST service?

That's why I initially thought to reuse ConnId connectors for this purpose.

WDYT?
Regards.
