ok this is interesting, I remember that I saw such a list long ago in WSFtp
also.

the least to say is that there is no ubiquitous way, in particular, some of
these methods could allow FTPS but many won't (because of mixes of things to
send to the real server, and things for the proxy).

I wonder if the standard method now is not simply to use HTTP proxy
tunneling and consider this FTP proxying as obsolete.
