Yeah, I dont see a big problem with files over 2000 lines in some cases, as long as things remain well writrej, organized, abstractd.

One piece of garbage that I'll never touch again hae most functions this size. One was 50,000 lines! Hundreds.of lines of if/else, half of the functions passed the same 60 arguments because he didn't understand classes or even dictionaries, etc etc. And was used heavily.
