MIE is preventing an entire exploit category permanently. Blastdoor is just being more careful in a specific area of the code. It's also not just a case of is it possible to exploit or not, but how much does it cost to develop an exploit, and how long do they last for. If it costs you millions of dollars for an exploit that gets patched a week after it's deployed, you can't use that for mass surveillance. If it costs you hundreds of millions, you can hardly use it for targeted attacks either. The cost of exploiting phones is constantly going up. It used to be within the ability of a single hobbyist developing a jailbreak. Now it's only in reach of the most well funded hacking groups for highly targeted attacks.
