There's a real cost. What's your estimate for going through each of these 190 patches individually, looking at the context of the code change, and whether the "ref counting or whatever" bug fix is real, and doing some real testing to ensure that?

That looks like quite some significant effort. Now if most of those fixes were real, now after the revert there will be 190 known bugs in the kernel, before it's all cleaned up. That may have some cost too.

Looks like a large and expensive mess someone other than that UNI will have to clean out, because they're not trustworthy, ATM.
