This doesn’t sound like a Szabo argument to me, do you have a link?
In any case, if it’s this kind of bandwidth consumption you’re worried about, you are free to use filters, or better yet run your node in blocksonly mode. (Bitcoin Core allows you to configure both, fwiw.)
I definitely use filters in my node, and I’m riled up on the fact that they are
a) changing the filter standardness
b) plan to deprecate one of the filters I use.
My trust in core developers has broken.
You don't have to upgrade at all if you don't want to of course.
(But fyi nothing has been deprecated.)
