Not an issue, just trust model differences that were not explained fully, but kasplex assumes a optimistic model for sequencing while i believe final settlement is still done by kas l1, igra on the otherhand is trying to implement zk from the getgo with kaspa's assuming the full sequecing and settlement.
Tldr(if im not mistaken)
Kasplex l2 (semi based approach, initially)
Sequecing: kasplex own nodes
Settlement: kaspa
Execution: kasplex
Igra(based zk rollup)
Sequecing: kaspa
Settlement: kaspa
Execution: igra
The point, i believe, shai makes is that kasplex is already in motion with a launch ready product that enables stables but is not fully trustless(yet)
