We already have that for most hardware in practice, don't we ? The direction of travel in the embedded industry seems fairly clear: you have totally-open ecosystems strictly for hobbyists (arduino, raspberry pi, etc), and totally-closed products for the masses (standard brands). Anything inbetween is tolerated but unsupported.

Clearer legislation would obviously not kill the hobbyist ecosystem, and possibly improve the branded one. Even if the price of such legislation were to be the loss of grey areas where hacked/unsupported branded products live, it might well be worth paying to cash in the gains. Obviously the devil would be in the details of such legislation, so it's all pure speculation anyway.
