It's been 7 months and DFT has been removed, can Kayn be viable in lane again?

You could bring back the DoT interaction with his passive, which mostly effected his laning phase, because DFT no longer exists to give him 8 orbs her W.

Riot said if the change that effectively removed lane Kayn impacted lane Kayn harshly they would buff him. 7 months later and lane Kayn is still god awful. I've got 2 secondary sources to account for this: 1 2

The designer who both made Kayn and also pushed for the change that removed lane Kayn had stated twice that Kayn should be playable in lane. 1 2
