Based on previous Hannes's work.
He wrote:
"And for several versions (years, even) the linux kernel has the ability
to correctly detect the device handler, so we should be making
'retain_hw_handler' the default.
And if we do this we also want to enable 'detect_prio', to ensure
we pick the correct prioritizer."
