Read / Write from/to ftp/sftp/scp etc. source/target directly in Workbench

Please add more documentation and functionality to make the SFTP capability in workbench viable. Current documentation is outdated. Further clarification/development needed on what is currently available.

I can successfully upload files to ftp/sftp using the FTPCaller and using hints shared in this question thread: https://community.safe.com/s/question/0D54Q000080hB29SAE/ftp-caller-error-in-the-ssh-layerDoes the idea shared on the current page suggest that there is a solution for writing output directly to ftp/sftp without first storing the data locally? If yes, where is it exactly implemented in FME Desktop? One alternative I could look for is a solution for writing my data locally (using a FeatureWriter) and upload the data right away using a FTPCaller with of course a mechanism deleting the local file as soon as its upload is successful. I have to produce and share a massive amount of data in batch and need to prevent consuming too much local storage.

Reading from SFTP and SCP definitely. In this age of internet insecurity, it's odd to have support for FTP but neither of those two (Doing it with Python is a bit of a chore).
