I guess the simple answer is that ||
is a boolean operator: and in C, a "boolean" is 0 or 1. The operands are implicitly converted to booleans (I have not checked that that's what the spec actually says, but it's how C behaves), and the result is a boolean.
Altering the semantics to support this pattern may well be feasible -- until someone relies on ||
doing what it's always done.
