I specifically wrote about the future where this amount may not be trivial.

But that's the thing, the game theory isn't about the HTLC amount being small. It's that closing a channel costs fees greater than the amount. So you can't make a profit from this attack.

We probably will have to tweak certain aspects of LN implementations to make sure this logic actually holds up in all cases. But the basic idea is sound.
