Marek requested that all gallium drivers default to enable the
extension and software primitive restart when required like today, but
that all non-gallium drivers not use the software primitive restart by
default, and not advertise support for the extension.
Would that work for you?
With this approach, simply using
MESA_EXTENSION_OVERRIDE=GL_NV_primitive_restart on a non-gallium
driver would not work, but it would match what happens today...
