The CA infrastructure stinks and is proven compromised and alternatives should be invented but PKI is a decades old problem and has never been satisfactorily solved anywhere.
I can't readily grasp the confusion of ideas and general brokenness of a brain that farts this proposition, to implement something known to be dysfunctional. Let's prolong the life of a broken piece of crap that should never have existed in the first place and in any event should have died long ago. Let's continuate as much of the stupidity of the old world as humanly possible.
Roughly equivalent, let's put three ounces of dog shit inside the car's tire, because there's no clear mechanism through which food would be contaminated by this, and therefore why not. So there you have the
power rangers, on their hands and knees in a parking lot somewhere, huddled around this old rusty clunker of a car missing one door, stuffing dog shit through the air intake.
If this is the sort of ideas you'd entertain it's at least understandable why you wouldn't see what the problem is with them.
