No-one says that HAL can't optionally depend on liblomoco; it might even
make sense to have this kind of "driver code" in a separate project if
there's the usual ABI/API guarantees, it's designed in a way so it's
easy to use from an addon / singleton-addon etc.

What I do think makes sense is having this information exposed in HAL;
it's really a lot easier for applications to access the information
through HAL that using a domain-specific library with it's own device
model. Another angle is device permissions; with HAL, since everything
is IPC, you don't have to ensure that the unprivileged user can access
the device file.

I'm sorry if this mail is not more helpful; I think I understand the
domain specific problems you're trying to express - but am not sure how
to address them without diving into the problems myself.
