This sounds good to me, I wonder what that different scenario could
be. Is it worth trying implementing that (i.e. would such patch be
even considered)?

The problem is not new apps, but legacy ones. Pandora is spiritual
successor of Gamepark/GPH devices, which only had OSS drivers, so we
have many apps/games outputing through OSS, some of them without
source available. We will have to provide userspace OSS emulation at
least, and in-kernel OSS emulation is attractive because of
performance reasons.
