Yes, ifconfig uses ioctl, ip uses a netlink socket.

That hasn’t happened yet and in any case is an implementation detail; if
anyone cared to keep ifconfig &c going after that point, they could be
modified to use netlink instead.

(Linux has a fairly strong tradition against breaking the user-facing
API, but I don’t know if an exception exists in this case.)

I’ve no idea what this is supposed to mean. If you want it to provide
basic functionality in a backward compatible way it doesn’t matter what
kernel API it uses. At any rate, I think it does do that.
