Something to consider for when there are more submissions of PWAD's later down the line: perhaps subcategorize Doom runs by which IWAD (doom.wad, doom2.wad, plutonia.wad, or tnt.wad) it uses. There are plenty of source ports that produce vanilla-compatible demos across many hardware and software platforms—basically as if Doom were its own platform with many emulators that could reliably produce console-verified input files. The IWAD has the vital guts that you're supposed to pay for.
Other things to consider: pretty much all demos submitted here will be at complevel 1.9, but there are some PWAD's that only work with older versions of the engine. Are those older versions to be handled separately if Doom gets its own section?

If you want tru dos authenticity, do you have to use an older version of the engine?
