I guess most new users forget one thing, and it's the main reason I do not agree with it (but I do understand it). The dev section was originially started as place for tweaked roms because source was not available. Even some themed tweaked roms appeared so roms also looked different compared to stock roms. You just can't say all themed roms do not belong there.
Even binary ports do belong there because you need to know how our rom works (dev knowledge)
I guess if we will follow the same thoughts for roms build from source, most roms were build using device an vendor folders from mik9, later adfad666 and now Lupohirps sources.
So no real developing there. (I know some changes to ported source are needed, but nonetheless following the same thoughts as expressed here).
And one other thing that is irritating me is that a lot of users agreeing here never developed anything and most of them only complain about ETA's and draining batteries etc. and never added anything usefull. I know we devs need feedback, but please... post usefull feedback and stop complaining about enthousiastics who take the time to play with android and learn from it, because that is how you learn to develop.
