Nevertheless, those tires on that race wore down to the bare white canvas, it was clearly visible, and they didn't fail. Everyone knows this is nigh on impossible with the pirellis. Also, you could have tires made to perform to specific distance and still keep going on the canvas if it came to it, but pirelli simply can't, or choose not to. More likely the former.
edit: JRindt has worded it better.
I can guarantee you, those tires would have failed just as easily or similar if they had been compromised by debris. Also, that race you are referring to, wasn't Silverstone, and I'll repeat, not under the same cars, with the same downforce and the tires being subject to the same amount of load. You are therefore comparing apples and oranges.

Formula 1 wants tyres from Pirelli to gradually lose their grip and get slower over a certain number of laps and then fall off the cliff. That’s it. No less, no more.
They’re not supposed to delaminate. They’re not supposed to blister, grain or become risky to use at low pressures (Ironically, one of the reasons touted for yesterday’s failures was higher pressures of 25 psi for fronts, according to F1.com).
They’re certainly not supposed to deflate(as suspected for Kvyat’s crash) or explode at random.
Arguably, that isn't as easy as one would think. Think about it; they aren't asked to make the most durable tire, they were asked to design a tire that only lasts a number of laps and then have a cliff. This is contra to what Bridgestone or any other tire manufacturer was ever asked of doing.
In other words, we want tires to have a limited tire life, but at the same time we also want them to be indestructible when going over that limit. Sounds pretty contradictory to me.
And then adding to having to design delicate
tires, they also have to factor in different loads, different strategic elements, drivers happy to go over curbs, some more aggressive than others, then there are different climate conditions to consider.
The amusing thing is, people will bitch anyway. They will bitch about the tires when they don't self destruct and barely degrade and thus produce boring races (Socchi). On the other hand, when they do happen to produce a spectacle and unpredictability (high deg) people bitch and moan too. Quite frankly, I'm amazed Pirelli is still happy to produce these tires according to the wishes of F1 as it seemingly is lose/lose.
