There should be a large group of people outside of BitcoinTalk that are passionate enough and willing to provide enough liquidity to boot-strap the pool, no?
The large group of people outside of Bitcointalk who are interested in coinjoins are predominantly using Samourai/Sparrow/Whirlpool.
How large? Because that's actually good because it could show that there's enough user-demand for different implementations of CoinJoin apps.
Plus it's always good for different open source projects to compete against one another, it makes them better. And it also gives the users something to choose from.
As I've said 100 times already, even putting the whole mass surveillance thing to one side why would people abandon a better coinjoin implementation in order to bootstrap an inferior one which suffers from address reuse and deterministic links?
I can't truly verify what's better/worse, but from what I read and hear on the matter, I think it's debatable. Why would Peter Todd, who has a reputation to uphold, say "Scamourai" could be a CIA OP.
