Every problem can be solved in many different ways. If you think you've already got use-after-free bugs under control, then more power to you! You absolutely have to concentrate your effort on whatever your biggest problems are.

But I'll also say that if you don't have any use-after-free bugs in the history of a large C codebase... you might not even be on the lookout for them? I still have them sometimes, mainly when it comes to multiple ownership. And those are just the ones I found eventually.

So yes, different strokes for different folks, but if you make the effort to incorporate tricks like this into your "unconscious" coding style, the ongoing effort is pretty minimal. Even if you decide this trick isn't worth it, there are countless others that you might find worthwhile. I'm always on the lookout for better ways of doing things.

I meant no use-after-free bugs in production, otherwise we find a lot in development with daily tests etc. but looks like we catch them pretty effectively. It works good for us but doesn’t mean it’ll work for all other projects, so yeah I can imagine myself applying such tricks to a project some time, especially when you jump to another project which has messy code, you become paranoid and start to ‘fix’ possible crash scenarios proactively :)
