For example, clients can query SMTs with:

Proposed Changes
The new endpoints are described in the API Spec above.
...
Future plugins will be expected to be reported in the generic `/plugins` endpoint. It would also be expected that the plugin-type be reported via their own `/plugins/{plugin-type}` endpoints.
Deprecation of existing endpoint GET /connector-plugins
It is further proposed that the existing endpoint `GET /connector-plugins` is deprecated. While there is no hurry to remove it from the codebase, the current `GET /connector-plugins` endpoint will be redundant to this new, more generally useful endpoint. Marking deprecation with the introduction of the new feature will give clients as much time as possible to migrate, giving the maintainers more flexibility to remove the old endpoint when they deem necessary.
Rejected Alternatives
Limiting scope of KIP to just SMTs
