I’m not sure I buy that there are that many links encoded as FTP that you’d hit during normal browsing. Chrome dropped support a year or so ago, so any website depended on FTP already has required a separate FTP client for 85% of users. It also doesn't really do a good job of transferring files - the protocol is slow and is incompatible with lots of firewall setups.
