Can you elaborate? I thought eBPF was created to be used in high performance scenarios, so I am confused why this shouldn't be posssible.

eBPF runs in an extremely constrained environment, in order to protect the kernel. indeed, it's quite high performance. but not high flexibility.

I have, but in the scopes of Kprobes non-network but memory. Here, I am sure you haven't at this point. I also provided projects you may check prior stating another nonsense. Instead, you could also provide some more evidence you disagree with.
