I don't think its absurd at all. It isn't required in anyway (opt in), lets you use your own keys (no preinstalled microsoft or other bigcorp keys), and isn't possible for someone to modify what keys you installed.

Of course if you lose your keys you can't sign anything else and that would make it basically ewaste, but most things end up as waste when you take actions that are reckless and can't be reversed (which is what losing the keys would be). Plus tech tends to ends up as ewaste after less than a decade anyways. Like sure you could still be using an AMD steamroller CPU but realistically after 10 years you'd be better off using a cheaper more power efficient chip anyways.
