Yeah, I don't doubt this. In fact, we could arguably provide the same
through some kind of common stack.

I sort of have to believe though that it's even more limiting that we
*don't* have any common interfaces, since that means you'll have to
rewrite your software even if you just want to switch to a different
Qualcomm modem (e.g. PCIe instead of USB).
