Would it be possible and a good idea to have a language feature
that allows some exceptions to use error code code generation.
If I understand correctly, you want C/Go style error codes when a
function fails rather than exceptions?
This is possible, it's just not used by Phobos. Just use
std.variant and have your function return the value on success
and the error value on failure.
