Handmade quoting is not enough for strings which contain double-quote
character.
See:

import std.stdio;
void main() {
  string s = `Hello "D" world!`;
  writefln("[%(%s%)]", [s]);
}

will output:
["Hello \"D\" world!"]

By design, std.format.formatValue functions stringize values by using
unformattable representation with unformatValue functions by default.
That's the reason why automatic quoting is done by default.
