Yes. The design I opted for instead ejects trolls from the signing ceremony if they fail to send in all requisite signatures, or send invalid signatures. Everyone else just restarts the signing ceremony without the trolls, but this time their admission fee is already paid, because they paid it the first time, so there's no need to pay again.
This model disincentivizes trolls; it costs them money to join the ceremony but refuse to sign (or give an invalid signature), but no one else is effected except that they restart the ceremony. In my tests with 11 people, the ceremony takes about 30 seconds, and if 1 user was a troll, it takes an additional amount of time that is slightly less than the original amount, due to having one less person. (So something like 30 seconds for the first try + 25 seconds for the second try.)
Another factor about anonymous coordinators: my hope is that users who have Umbrel nodes or similar will also run my coinpool software and thus onboard their friends and family to bitcoin. This is, in my opinion, safer than doing so via LNBits or LNDhub because those solutions are custodial, and if your Umbrel gets fried while your friends and family have their money on it, they can lose that money.
My coinpool software, by contrast, is self-custodial, so if your Umbrel gets fried, all it means is your users have to use their unilateral exit transactions to get out of the pool. That seems safer to me and thus more likely to appeal to the types of hardcore bitcoiners who purchase Umbrels and similar node boxes.
