The extra data in the object file comes from the inclusion of

there as well, which will always be larger than the actual
string passed to hexString).
I also see the data in there twice for some reason.
This is no longer the case with the PR.
import std.conv;
void test() {
__gshared immutable char[4] s = hexString!"deadbeef";
}
produces the following, with no sign of the template and the
data is there only once:
_DATA segment
_D5test24testFZ1syG4a:
db 0ffffffdeh,0ffffffadh,0ffffffbeh,0ffffffefh ;....
_DATA ends
But it looks like they are all dchar, so 4x the space vs
x"deadbeef"?
