That sounds good, but if you have a PMO and an enterprise Change Control Board that controls your not-quite-CI/CD deployments, you may find yourself hamstrung. I've been in that position before, where there was simultaneously a bottleneck of clear requirements and also a bunch of stuff (tech debt, small features, bug fixes, UI tweaks) sitting and waiting on a branch ready to deploy when downtime was finally approved. Or, situations where enterprise policy requires human SQA signoff on everything going to prod. There are lots of places you can create inefficiencies in the system and lack of approved requirements is just one.
