In a world where Monero exists there is no need for a sub par federated chain like Liquid.
LN has a couple of attack vectors and a severe one has only been revealed yesterday. It's privacy is very limited in comparison to Monero. I use LN myself, but I will never entrust it with serious sums >$100.
Plenty of services were built by Bitcoiners and later opened to other chains. The same is happening with Monero btw, where Cake and Stake started as Monero only to later open for more customer choice.
Haveno is indeed a project many are wating for for a long time (1 year since ETA). But in the meanwhile bisq does a perfect job and I'd highly recommende it to everybody.
