I don't think that's true either. I don't agree with your root cause analysis or your bogeyman selection. it became normalized to tell transactions directly to miners when blocks first started being full. this is what opened up the can of worms with nonstandard-but-valid transactions becoming more common than they were before. if you still want to blame core for something, you can blame them for this.

sorry, you're wrong again. mara slipstream is currently in operation and can be accessed here:
here is an example of a nonstandard transaction that they included recently. it was never in the mempool.

The haven't stopped their Slipstream.
They have stopped accepting transactions with sub 1 sat per vB fees because of the nodes policies ...
and these node policies deter slipstream from including some types of nonstandardness but not others because?
deter mass abuse
I mean if I ran this kind of thing I'd want extra on top of the going rate just because it's custom and costs extra to operate
Cheer a little bit, its funny I promise 😂😂🤣
