@atoulme IIRC this was a design choice. If the operator cannot watch for the collector CRDs, it wouldn't be able to do it's purpose? Can you explain more about the reasoning behind this request?

[atoulme]

My purpose is to use the operator only to instrument applications, and I run my collector deployment in a different manner.

[jaronoff97]

i understand that, but despite not running your collectors this way you can install the CRDs and do nothing with them. For optional CRDs that are not necessarily part of the project we can enable and disable some amount of this, but I'm not sure we would want to do this for the core collector functionality.

Why is that?
