option to never terminate 'kind: namespace'

[tooptoop4]

scenario:

1. cluster-admin sets up several namespaces
2. app1 starts using namespaceX, also deploying its own definition of namespaceX with kind: namespace inside its helm chart
3. app2 starts using namespaceX
4. app1 is decommed, helm chart removed....this inadvertently puts namespaceX into Terminating state
5. issues start for app2, no new sync can happen because the namespace is in Terminating state, there doesn't seem to be anyway to cancel termination of namespace. finalisers prevent namespaceX from being totally deleted but even Terminating state means no syncs can happen

would be great if argocd had option to never set any namespace to terminating state (or even deletion)

This has potentially been resolved with argoproj/gitops-engine#524, can you confirm?
