I wouldn't oppose a patch to add back the non-mq path, but as far as I know nobody is working on it. It's not hard and I can help if you need guidance. Adding I/O scheduler support to blk-mq has been promised for at least a year now, but I'm not aware of which kernel release might have the work. It's not even been submitted to LKML, so I guess it's quite far away.
