If it takes no time, then it takes no thought either. It will just become muscle memory and you’ll click it before catching yourself saying ‘oops’. Besides, I FUCKING HATE meaningless popups of all sorts, and I know I’m not the only one.
If you have encountered a problem, then it’s a bug and you should file it.
If you truly work directly on superdense meshes all day and feel you really need a confirmation dialog, then I suggest you write yourself a small addon that adds that popup confirmation. No, seriously, try it. I promise it’s easy. You can then share it with like-minded heavy mesh editors. (Or just keep it to yourself, like I do with my small improvements, so you don’t have to maintain them for others. Whatever floats your boat.)
