Is self referencing declarative config safe?

[couling]

I've just got my local testing cluster into a bit of a mess and need to fix things on the kubectl CLI.

What I did was try to make a master app for declarative setup of projects and try to make it declare itself. On the face of it, this looks like it should work since the initial manual config will immediately be replaced by the declarative one in the project itself.

The mess I created was trying to remove this. I think the finalizers effectively deadlocked with the app becoming classed as a child resource of itself and so waiting for itself to be removed before it could be removed. A few kubectl patch statements later and it all disappeared.

So my question is whether this is the only "got ya"? Is it self to have an app declare itself?
