@mimowo @tenzen-y this is ready for a review again.

[mimowo]

Suggested change

	// +kubebuilder:validation:MaxItems=64
	// +kubebuilder:validation:MaxItems=100000

This number can be large, this is the number of nodes essentially

[mimowo]

This type is going to be removed anyway, so maybe just mark it no lint?

[mimowo]

Another pass, I think when these are applied I'm happy to merge the PR.

cc @tenzen-y if you could also give it another pass
