Sure, if those functions added were related to configuring network interfaces, but it would be odd if someone added functions for configuring storage controllers.
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.
