From parent: "Depends a lot on the usecase of course." The usecase that I see most often of SFTP (and hinted at in the parent's problem description) is generating one-off reports for third parties, or passing data to vendors who are stuck in the 90s, like financial services companies. It's almost always read only (or read and delete), in which case implementing an API like this is pretty straightforward. Log unsupported commands perhaps and decide if you want to implement them later.
