Sure, if those functions added were related to configuring network interfaces, but it would be odd if someone added functions for configuring storage controllers.
BitTorrent transfers files, so should a BT client be bolted on too? Typically the Unix philosophy has been do one thing well, not do all the things.
The sticking point is always what "one thing" is. I can certainly see an argument for "download a file over http" (or, for another program, ftp), but I can also see an argument for "download files over the internet". In which case, honestly the only reason I'd even quirk an eyebrow at a BSD's ftp(1) adding bittorrent support is that bittorrent usually means running a daemon that that does feel out of character for it. But even then I wouldn't be that surprised to see it added.
