In a proposal for Bisq 2 a major change in the trading protocol is suggested with having BSQ bonds paid by traders.
The DAO/BSQ concept is already too complex for an average Bitcoin holder. And for now it is coherently optional to buy BSQ, hence holding stakes.
If mandatory BSQ bonds is added users are forced into DAO, giving a much higher threshold to start and continue using Bisq, with likely undesirable impact on exchange liquidity (including fees).
It is good the DAO module is optional to use now. A complete non-contributor can preferable disable it and get huge improvement in app performance.
Keeping things simple and optional by not enforcing indirect contribution with BSQ bonds (or BSQ fees) is a more future-proof approach imo.
