In what possible way is that an improvement ?

I agree with Robert. It is not an improvement.

For various reasons, in some parts of our systems, we have to manually create ports beforehand and it has always been a mess.

Instance creation often fails for all sort of reasons and it's really annoying to have to garbage collect orphan ports once in a while. The typically user does not use the API and does not care about the underlying details.

In other parts of our systems, we do rely on port auto-creation. It might has its flaws but when we use it, it works like a charm and we like it. We really appreciate the orchestration and automation made by Nova.

IMO, moving the burden of such orchestration (and garbage collection) to the end users would be a mistake. It's not a good UX at all.

I could say that removing auto-creation is like having to create your volume (from an image) before booting on it. Before BDMv2, that's what we had to do and it wasn't cool at all. We had to implement a logic waiting for the volume to be 'available' before booting on it otherwise Nova would complain about the volume not being available. Now that we have BDMv2, it's a much better UX.

I want to be able to run this command and not worry about pre-steps:

  nova boot --num-instances=50 [...] app.example.org
