BIP155 was deployed in Bitcoin Core version v0.21.0, and has been in use for almost 5 years.

New networks may be added to the reserved network IDs table, when they're needed, either in this BIP (seems fine) or in a new one.

If BIP3 is activated, I think BIP155 would become Deployed.

Seems reasonable, but probably would be fine to move it to Final directly.

I hope BIP 3 will move forward soon, the BIP 3 activation PR is in conflict with everything in this repository. :-/

Thank you! Sounds good to me (either like this, or Final). About time, even, as BIP155 was introduced in bitcoin core version v0.21.0, and has been in use for almost 5 years.

The only change i can imagine would be adding new network types, when they're needed. But those could be defined in a new BIP as well. That's no reason to keep it as Draft.
