What's interesting is that tech is very precise and yet plumbing is not (it's analog with some margin for error just like cooking as another example). But both of those things have been around for much longer than tech so perhaps the roles are clearly defined for that reason. (You probably could find counter examples of course.) Maybe this stems from the fact that the general public doesn't typically deal with "computer guys" [1] so they have no need to differentiate them. But they do need plumbers, carpenters and electricians and they know what they are. [2] (And those are also union jobs so that probably also makes titles necessary). [1] How many times have you heard "he does something with computers?". [2] Maybe this all stems from the fact that there was no central defining authority at any point that made any statement as to what the titles meant. Even in religion there are clearly defined titles, right? In tech (on the net at least) what do we have? RFC's a nice way of asking opinions.
