📝 Original message:
Thanks for instigating this, Rusty! 0conf/turbo channels have been hackable
for a long time, and we would love to unlock new user experiences for our
platforms with it, formally if possible.

0conf is desired by every wallet, every LN exchange, and truly shows off
something only LN can uniquely offer as a UX.

We are happy to support how we can, and answer any questions from the
trenches.
