Has the old ATA 'queuing' feature been removed from

I would hope that old ATA queuing feature would be removed. It adds too
much complexity to an implementation, unless the host controller
provides some assistance. Even with "smart" host controllers, error
handling is still complex.
I call it "legacy TCQ", and don't bother to implement it in Linux.
