You seem to understand what I'm saying and agree with me Literally the opposite. Your initial statement was Measuring memory usage is hard on a modern OS. Which you've agreed was false as /proc/$PID/maps is easy to read. Then said: Defining it is what's hard But these statements are not mutually inclusive nor does the later imply the former. I stated measuring is literally the simplest thing. You said ah but what you measuring. That isn't dependent on the tools, or OS. So why did you state it was?
