Now that the default keys are changing, the default debug key bindings should be removed as well. Very few of them are actually useful for normal users. Leave the cheat menu(alt+F2) and the change skin(alt+arrow, you need it for the bugged replay UI) but disable everything else as they only cause issues. F9 for the error log is absolute cancer for fullscreen players, for example.
I believe this should happen for all players, not just new install as the amount of players who'd benefit from keeping them is really small. If you're a dev, tester or caster you can enable the ones you need.
