Why do you want to keep bio-based dm-multipath? In the realistic environment, dm-multipath is usually the bottom of the stacking devices. So I think existing working configurations are still possible with request-based dm-multipath. If we keep both types of multipath targets, maintenance cost would be doubled and additional user interface might be needed to specify which type is used. I can't see any major benefit worth paying the cost of keeping bio-based dm-multipath. I know dm developers sometimes use linear/error maps under multipath just for testing purpose. If that is your requirement, I can make request-based targets for linear and error (e.g. named like linear_rq and error_rq).
