This will have better longevity as new releases are less likely to require patching since they are ~usually~ on occasion submitted upstream

I don't follow. What are you suggesting?

I'm also not sure if it statistically correct that most patches are submitted upstream 🤔

[prince-chrismc]

Still early morning ☕ sorry!

I see the diff below in lots of PRs and I think it's better to start with it so that it does not require a RREV and rebuilding more packages just a small bump would have been sufficient
