What if status is SUCCESSFUL
?

Only when Decommission has failed, we can allow the weight update can go through. Not for any other status

Isn't SUCCESSFUL
a final state? The error message of this if
condition says: a decommission action is ongoing with status...

A succesful decommission state means the transport execution has completed. The nodes are decommissioned in this state (not able to start pre voting or join). Hence DecommissionAction ongoing means a zone is decommissioned and the cluster rejects pings from decommissioned node

If decommission status is FAILED can certain nodes be out of service or decommissioned while others not as in partially failed?

No, if the decommission is FAILED
, joins or prevoting is not blocked on those nodes and hence if some nodes are out of service (which can happen), the weights request can go through

But then the zone isn't fully equipped to take traffic right like 90% nodes are out of service and we place weights 10:1:1 when 10 is for the zone only operating at 10% capacity?
