Yeah... I'm not sure I see an alternative to this being what most people do, unless spam filters somehow win an arms race when it's an uphill battle. But, assuming this replaced AI spam filters rather than being used together, is it any worse than your friend's (or your mailing list member's) email getting classified as spam? At least this way you know they didn't receive it and if you really did care about them specifically you have recourse. If it was just silently classified as spam you don't even know they didn't get it until weeks or months later if they ever notice it in the first place.
