They are without a doubt extremely useful for catching mistakes, but
having them on in released code is absolutely antithetical to the design
principles of the STL and of generic programming in general, which
strives to raise components to the highest level of abstraction
**without loss of efficiency**.  If I understand correctly, it also
causes the library not to meed the standard's performance requirements.

Anyway, I agree that we must make it easy, if not the default, to
install libraries compatible with the MS default ABI.
