If removing (non-mining) transaction dust and the resulting bloat is "trivial" then why is XMR lagging behind BBR in implementing that feature?
Stop being a troll and an idiot please.
Look at the BBR list of features and I quote (with bold emphasis added):
Removed Dust from block reward to reduce block chain size even more
The change in BBR is removing of mining dust, as I said.
XMR does remove non-mining dust. You obviously don't understand the handling of dust in the cryptonote design. It is somewhat clever.
