lftp parallel put?

[Alexander V. Lukyanov]

I have a question though: there is a parallel get, why is there no parallel put?

Remote file access is more difficult and sometimes not so reliable as local
access. Ftp protocol was the first supported one and the semantics of
REST+STOR commands was not quite clear and servers could implement it
differently. E.g. some could truncate the file.

Currently, pput could be implemented for selected protocols, like sftp.
But generally it would not be quite reliable for others.
