I'm not opposed to warnings that may have false positives. That's why
they are warnings rather than errors.

My point here is different. Imagine the documentation for the new

  Warns if `x && y || z` cannot be proven through static analysis to
  be equivalent to `if x; then y; else z; fi`.

Doesn't this strike you as odd? If the latter construct has the
desired semantics, why not use it in the first place? It'll obviate
the need for a new warning and convey the intention to humans reading
the code.
