Interesting. FWIW, I believe that multi-asset LN will fail for a
related, but different reason: to prevent long-lived spam payments we
may require proof that something went wrong (ie. channel unilateral
close tx). That won't be valid if it's from a different network,
resulting in the exchange point itself being penalized. Thus they are
vulnerable to such a DoS.
Cheers,
Rusty.
