True. Yet, cases like IR devices made by someone's own use is something
that we don't need to care to have an in-kernel driver.

I don't see any reason why not supporting STB protocols. Several such
hardware use Linux, anyway. So, eventually the STB manufacturers may send
us decoders that work with their IR's.
