This would definitely make sense for the lists of services and channels.

Not so much for interaction with adapters, of course.

Mmm, what is reason that prevents us from leveraging HTTP Cache for channels/get as well?

I guess we could ask Adapters to provide an Etag if they want to support caching fetch operations.

Yep, that would probably work, but will basically tie adapters to HTTP and introduce more complexity inside adapter :/

Can't REST layer somehow determine (before or after serialization) that response it's going to return hasn't changed? It will also cover http requests that consist of multiple "adapter fetch requests" that we use currently (and it's pretty awesome feature btw!).
