Goal

Unify the CRD upgrade safety check logic across releases by using the crdify library.
Ensure 4.19 and 4.18 also include all fixes and the same behavior, even with Go version limits.

Why

• Current custom code in ≤4.19 is hard to maintain and prone to bugs.

• crdify already includes the right validation logic upstream.

Limitations

• Each crdify release ties to specific Go/Kubernetes versions — older releases can’t upgrade Go, so we need a workaround.

Plan

• Use kubernetes-sigs/crdify directly for all versions up 4.18 ( if possible, ensure all code changes; bug fixes so far )

• For 4.19 and 4.18:

• • The Go version blocks upstream import, fork or embed the crdify code under openshift/ org or our repo.

• • Make sure it compiles without Go version bumps.

• • (Ideally) Verify we have all recent bug fixes. See if we can ensure sthe ame code from the latest to 4.18 as much as possible.
