Pull Request Checklist

Pull request is based on the develop branch
Pull request includes a changelog file. The entry should:
- Be a short description of your change which makes sense to users. "Fixed a bug that prevented receiving messages from other servers." instead of "Moved X method from EventStore to EventWorkerStore.".
- Use markdown where necessary, mostly for code blocks.
- End with either a period (.) or an exclamation mark (!).
- Start with a capital letter.
- Feel free to credit yourself, by adding a sentence "Contributed by @github_username." or "Contributed by [Your Name]." to the end of the entry.
Code style is correct

Is it okay to add the to_key arg to the get_new_events(...) signature even though there is a EventSource.get_new_events(...) abstract method?

I noticed the presence variation seems to do it

It's fine to add extra optional arguments to overrides (as its still compatible wit the base class)

We should find a better way of tracking the rooms than via the sync ops at some point, given we want to remove them.

When we remove the ops, we will just get a straight list here instead of needing to dive a few levels into the ops. Doesn't seem like a problem

FWIW it won't necessarily need an index, doing filtering in the DB still reduces the amount of work that needs to be done.
