This is a tough one.

On one hand, having two interfaces means, well, having two interfaces.
On the other, the Interrupt interface is an HIL interface (e.g., the
MSP430Interrupt interface has more functionality). Allowing additional
parameters that could be invalid (e.g., making it take an
interrupt_edge_t of HIGH_TO_LOW LOW_TO_HIGH or CHANGE) goes against
static binding, in that the error is at runtime.
