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.

I have a little problem with this statement you made:
"Sure, on occasion someone might lose a few sats from a counterparty closing a channel at the right moment to steal a dust HTLC".

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

But yeah, I can see many people actually knew that there is such a thing. I didn't know until today..
