If you read the OP it says that their support for FTP is already pretty limited. Doesn't support encrypted FTP (FTPS) or proxies. Kinda goes against the effort they're making to push encrypted connections with HTTP.

They'd have to spend time and effort getting their implementation up to scratch.

Kinda makes sense to scrap the FTP support as there's not much of a user base and leave it to dedicated software like FileZilla/WinSCP/CyberDuck etc. etc.
