Feature request: allow specifying `feature_mjolnir` rooms in the `config.json`

[Mikaela]

Your use case

What would you like to do?

I would like to specify feature_mjolnir banlist rooms in my config.json.

Why would you like to do it?

To my knowledge the option doesn't sync or doesn't get stored to account data and I would like to share the same ignore lists across multiple accounts that all share the same config.json that I keep copying around.

How would you like to achieve it?

I would like to have a block in config.json for this.

Have you considered any alternatives?

I could manually add the room subscriptions everywhere, but that is a lot of effort.

Additional context

The current situation is a lot of work, so I seldom get around to doing it regardless of having feature_mjolnir enabled in my config.json and loving it.

Mjolnir ban rooms are only stored in account data

Yes, I was informed of this at Matrix HQ. Regardless I would like to specify defaults in config.json either for myself or users of my Element Web instance as pointed out by @FSG-Cat.

It is more likely this labs flag be removed than any development be put into it at this time
