I generally agree, though I would add that I think this depends a lot on the skill set and technical background of the person. My gut feeling is that if someone is going to struggle with optimizing for a relatively fixed target like Fly (the billing is extremely predictable compared to some other offerings out there, if not completely fixed), the chances are that they won't be cut out to do double time taking on what is effectively a Linux sysadmin role.[1] [1] I may be completely wrong
