I would think it would help safety to know this as other companies may also be outsourcing safety critical software to the same country. Knowing the assumptions that a particular set of programmers may make would likely be a good thing.
If past aircraft accidents have taught us anything, it's that they are caused by a series of small events or defects all coming together. The holes in the Swiss cheese lining up as it were. Knowing that developers from X country will make this assumption is the kind of thing that would be taken note of in the industry. Doesn't mean they won't outsource, it just means they will be more precise with their specs.
It just closes one more of those tiny holes. So I'm not sure keeping shtum about where the software was developed is really in the spirit of openness that air accident investigators try to foster.
