I think it's safe to ignore Core / Knots
 drama and treat jpeg 
spam utxo bloat as a forcing 
function for eventual universal 
adoption of utreexo, including 
filtering nodes like knots that
 hate it but oh well too bad for them.

Given the economic incentives long term, 
I see no other way.

Spam is a sideshow indeed
 "like arguing about the Polkas" 
in good morning Vietnam is a good way to put it.
