VetoerSet Feature: request for PR guidance

[xenoliss]

Hi there,

I'm Baptiste from the Base team. I've been working on adding the VetoerSet feature to the Optimism smart contracts to allow any of its members to perform a veto across the entire Superchain. I believe this has already been discussed, and the PR is almost ready to be sent. However, since this is my first one, I'm opening this issue for some guidance.

The PR adds new smart contracts in packages/contracts-bedrock (implementation + tests). The code is available here.

I am unsure about the following:

1. Should I PR to the develop branch directly?
2. Should I generate a changeset? (When trying for now, I encountered an error that I need to investigate further if that's needed.)
3. Should I rebase on develop before sending the PR?
