The counter argument I would say is that having all these integer ids comes with many problems. You can't make em public cause they leak info. They are not unique across environments. Meaning you have to spin up a lot of bs envs to just run it. But retros are for complaining about test envs, right?

Uuid4 are only 224bits is a bs argument. Such a made up problem.

But a fair point is that one should use a sequential uuid to avoid fragmentation. One that has a time part.
