With the new rcat command, is there (or will there be) a list of backends where it’s supported?
I’m particularly interested in SFTP. While the protocol allows chunked uploads without a known final size, many tools (including the OpenSSH one) don’t support it.
Yes this will be in the overview page when the next release goes live. You can see here what it will look like - and Yes SFTP does stupport StreamUpload
