Since %zs is inherently unsafe, it

will
infect everything else that transitively calls writefln with
unsafety.
This makes %zs an unacceptable feature.
How does it hide anything if you have to explicitly mark the
format
specifier as %zs? It would be documented, just like it's
documented
that passing pointers to garbage-collected memory to the C side
is
inherently unsafe.
writefln cannot be @safe if it has to support an unsafe format
specifier. It's "hidden" because it affects every call to
writefln, even if it doesn't use the unsafe format specifier.
