Why not? There are already several, and it helps find bugs. Maybe you could convince libc++ to change as well if you want to keep the behavior the same?
It does slightly concern me that some users might actually semantically expect a moved-from string to be empty, even though that's not guaranteed, although for non-SSO cases it *is* guaranteed.
Is it? In debug mode, I'd be tempted to leave the string as "moved" (size 5, short string so there is no allocation).
