I would prefer:

to "group" the resources parameter together. When we add in trait

resource classes and traits other than just knowing resource classes
are ALL_CAPS...

OK, that’s fine. The URI path is still just 126 characters, well below
the limit of around 8K. It still seems anything but scary.
Oh, absolutely, I wasn't arguing about length of URI or anything.
To be clear, I could either go the above route or even do a POST
/resource_providers that returns a list of resource providers instead of
creating a resource provider. Don't mind either way.
But, we should definitely agree on which this is going to be ASAP.
Last time I was aware of the discussion, I thought that sophisticated
queries for a list of resource providers would involve specifying a
structured JSON payload. That is where I don't tend to think a query
string in the URI is so usable. Are we assuming user queries will be
relatively simple?
From what I recall, the ideas were:
1. GET with non-JSON query string if simple, else GET with JSON body
(which is not covered by HTTP spec)
2. GET with JSON query string to cover both simple and sophisticated queries
3. POST with JSON body to a /resource_providers/list URI to cover both
simple and sophisticated queries
Which option are we talking about now? 1? Or a version of it where
queries are assumed to be simple and no JSON structure at all?
