This particular usecase is unneeded once you have the "enter" ability.

Is that cheaper from a syscall count/cost?

Why does it matter? You told, that the usage scenario was to
add routes to container. If I do 2 syscalls instead of 1, is
it THAT worse?

i.e do I have to enter every time i want to write/read this fd?

No - you enter once, create a socket and do whatever you need
withing the enterned namespace.

How does poll/select work in that enter scenario?

Just like it used to before the enter.
