Some questions about jails

I've a few questions about jail(8) and hope you'll be so kind to answer
First of all: Why is procfs(5) required inside a jail (speaking about
5.x and 6) ? "
As procfs is considered deprecated due to its inherent security
risks",why should it be used inside a jail?
Second question: why does an "ifconfig" from inside a jail list every
network card present in the host system? Wouldn't it be better if only
lo0 and the interface with the jail IP are listed ? I think it will,
because it's my personal opinion (please refute me, I can be wrong) that
one jail's purpouses is to fool the jail users, making them believe that
they are inside a real system. I came to this conclusion reading about
security.jail.getfstatroot_only in jail(8).
Thank you in advance for your replies.
