FWIW, although that may be true for this use case, it’s useful to keep in mind that FTP encodes a large body of experience that, in some ways, HTTP continues to try to evolve to replicate (like letting IP be the multiplexing unit and automatically avoiding HOL blocking).

FTP isn’t quaint in that regard. It remains the gold standard in many ways and has many lessons still to offer.

(Lessons; not necessarily needed operationally)
