Ok, my memories were muddy, now I remember better: it is possible, but
without (2) and (3) it is unusable: there is no point in having two LFE
channels if the user cannot specify "the second one" or know which one
is which.

We get to decide what is a valid use case and what is not. And in this
case, since the devices and filter I quoted already behave like that, I
posit that it IS a valid use case. Therefore, this new API must be
capable of handling them.
