Automatic Arming

Hello developers,
please, would it be possible to add an option for automatic arming, as soon as all Pre-arm safety checks are OK? I done already two take-offs from hand without arming and I think I am not the only one… I tried to disable the arming by setting ARMING_REQUIRE to 0, but that is not I wanted - motor is armed already before checking is finished and I do not know, when the checking is done.
