I agree. The author's description of what is "reasonable" sounds like a blueprint for many of my late nights struggling with Windows:

"apps that assume that printing works will still behave in a reasonable manner: You’re just on a system that doesn’t have any printers and all attempts to install a printer are ineffective."

Maybe the underlying assumption is that the users will give up before spending an "unreasonable" amount of time on these tar pit features.
