Unless I completely misunderstand something, one of the main points of

Hmm, for me the main point was to keep the complete processing
of a single packet within one CPU/Core where this is a non-issue.
That was another main point, yes. And the endpoints should be as
little burden on the bottlenecks as possible. One bottleneck is the
receive interrupt, which shouldn't wait for cachelines from other cpus
too much.

They do it because life wouldn't have any meaning for them if they didn't.
That's why I draw cartoons. It's my life.
