That means you would only discover format string problems when
bootstrapping (unless you keep a build compiler around of the same
version).

For those developers working in cross environments, they would also have
to keep a native compiler of the same version installed to see the
warnings.  I think that is a poorer proposition, but that's just my 2
cents.
