All of those things already got reversed in the past. You just haven't heard of them because they don't really matter without you know, the support, software updates, the ecosystem and so on. What use do you have from one specific version of nvcc or the fw for one specific version of a watch? Your work will be obsolete with the next watch, that's why people haven't bothered so far.

Of course if it's cheaper, someone might, but the real barrier is really the whole first-party support, it's not the technical stuff.
