KPM can unbind keys in certain situations

Not sure what the steps were, but I'm pretty sure KPM was responsible because it was precisely these keys that were unbound: https://github.com/JonnyOThan/kOSPropMonitor/blob/7ee72a860c58c062f675f3fa73867a00d8d8ee6f/src/kOSPropMonitor/kPMCore.cs#L60

Can this be accomplished with input locks instead?
