What "downstream community"?  There is none, and you know it.

That is the whole point.  Voyager isn't just a driver -- it's an
odd-man-out variant of the most used architecture in the world.  If it
was just a driver, it would make sense.  However, its very existence
forces constraints on the upstream x86 architecture, and it imposes a
real and considerable workload on the upstream maintainers -- and that
is not you, but on us.  When that happens with drivers for obsolete
hardware, we remove them.

Hence, Ingo rather logically asks you to justify this impact on our
workload.  I would like to know as well.  I'm personally sick of the
extra overhead this museum piece imposes.
