If people don't have a preference for a specific accelerator, just need
"a working accelerator", then I think it is reasonable to assume they
won't want/need to pass options to the accelerators either.

"-accel default" is targetting the simple "do the right thing" use
case, so IMHO doesn't need to support per-accelerator options.
