Those effort are always a bit iffy since those very same companies go to great length to lock third party controllers out of their ecosystem, as well as fail to support even their very own controllers from previous console generations.
If real accessibility would be the goal, they could just open up their ecosystem and make proper use of USB and Bluetooth so everybody can build their own controller and keep using them across console generations as well as consoles from different manufacturers.
