I think this is a little smarter than that, it tries to fetch the actually relevant relays somehow, which is good, we shouldn't be relying on static lists of relays. Also the browser would probably crash.

Agreed

You can add them to the bootstrap list and you’re good to go. With the mutiny broadcast relay and your relays, it should have pretty solid coverage - nothing will be perfect. May not matter now, but as we scale, apps should only need to query your relays for your content. If it’s marked as deleted on them, then you’ve covered the largest base. Side note is I’m having a hard time finding even 150 reliable relays that are online and stable. Broadcasting to 1,750+ (which I’ve seen) and having 80% fail isn’t much of an improvement.
