I never understood why the Taproot proposal didn't include CISA.
Taproot transactions are not clearly cheaper than native SegWit, so there's no economic incentive to use them. But with CISA they would be.

I believe that's because the developers didn't feel it was ready yet, but here's the repo for it:

I'm totally onboard with CISA (when its ready), but I don't see it solving the multi-party channel problems the lightning devs are trying to solve. Covenants propose to solve some of the problems with multi-party channels, but not all of them.
