LGTM, I see no reason to reject this.

This being said, I’ll add that I could not find a way to get everything not lack balance at some point while trying to create lots of users. I eventually gave up on using multiple runners, hence the reason why https://github.com/near/nearcore/pull/11560 is suggested to run with a single locust process, which avoids the multiple workers complexity we otherwise have :)

I also had to disable gas price increases under congestion (basically set max_gas_price to min_gas_price) and that was enough for workers to avoid running out of funds.
