It would be noticeable in many cases.  It is these days quite usual to
connect to sites at decent bandwidth, but with less than impressive
latency, such as 300ms.  Every FTP command requires a round-trip, and
those add up fairly quickly.  The current Wget sends at least seven
commands before starting a download.  In my case it means three
seconds of chit-chat with the server before anything useful gets done.

I'm not sure if the designers of HTTP intentionally reduced the number
roundtrips in the protocol or if they just got lucky, but they did
exactly the right thing.
