Sounds sensible, but it means we now have metrics that don't rely on Tinybird events?

I was sure I wrote a reply here, but it's lost.

We already have some metrics that are still based on SQL for various reasons. The revenue ones are because we need to look up the FX rate, and some other ones we don't have the data in Tinybird.

For the seats, I think that maybe we could introduce events where they are missing and generate them via Tinybird, but I didn't feel like it warrants doing that before rolling these out, and then we can do it based on performance.
