Though I have to say it's quite sad that something like the ability to remap keyboard keys has become a contentious issue in game development. Fighting for credit for something that has/had been standard for decades is just WTF
I think (most) people respect the challenges of developing for the PC platform. Its just that like you said, we see devs touting things like keybindings as if they're doing you a huge favor.
