It's not that the front door won't stay shut, it's that different portals to the house seem to be locked or unlocked or just plain open sometimes at random intervals. There is benefit to an attacker to having a known ingress available on demand. There's a difference between a bug, a potentially exploitable bug, and an exploited bug. There's also a big difference between what's known and what's not yet known. Just because kernel developers are busy inadvertently introducing bugs doesn't mean that those bugs are all equally useful as an exploit. And that's before even considering that some bugs are easier to identify than others. A sophisticated adversary being able to get an exploitable bug into the kernel that they already have an exploit built for skips the discovery and exploit development phases, while also ensuring that the exploit delivers the type of access desired, rather than depending on luck. This is definitely something we should be thinking about.
