So now you have to pay attention to the condition of your crankset. (It wouldn't hurt to inspect other things now and then, too.) It will be obvious if the bond starts to go, but it will not go from perfect to sheared off in one ride.
Flip this around - knowing that Shimano makes cranks this way, would you buy a brand new Hollowtech crank? Why assume you'll be safe on one of those? Or a recall replacement for that matter?
Sure but if this has never happened to you, you have no idea how long it takes to go from absolutely fine to “on your arse on the tarmac”
Second question - seems more likely they’ll have learned what not to do from this.
