And the previous examples were language agnostic. In D and other
languages where the length of a string is stored we can nest strings
anywhere inside other strings.
const char[] a = "foofoo";
const char[] b = "oof";
Those can't be nested in null terminated strings, bit they can where
strings have an explicit length.
More to the point, does dmd perform this optimization currently?

No.
immutable string a = "123";
immutable string b = a;
void main(){writeln(a.ptr is b.ptr);} // "false"
