Good morning ZmnSCPxj,

> Of course, I know of no such technique, but given that a technique (Drivechains) which before would have required its own consensus change, turns out to be implementable inside recursive covenants, then I wonder if there are other things that would have required their own consensus change that are now *also* implementable purely in recursive covenants.

Agree. I would be interested to know what is NOT possible once we have recursive covenants.

> if there is *now* consensus that Drivechains are not bad, go ahead, add recursive covenants (but please can we add `SIGHASH_NOINPUT` and `OP_CTV` first?)

Agree and I think everything can be done in separate soft forks.
