Unfortunately this would break the idea of Linux distributions listing optional add-ons as dependencies of a package to make things easier for the user.
If this feature is abused enough to warrant review by whomever currently keeps download sites from just automatically installing the software (instead of their 'i'm technically not touching you' opt out crap) for any individual case, that case will feel the wrath of whatever banhammer the powers that be wield.
That doesn't actually solve the ambiguity. It just shifts it elsewhere.
