I'm not quite following the relationship between the two alternatives. Isn't the 
symbol version independent of whether we keep things as they are now, or install 
the patch that you proposed, or install that patch with my further suggestions? 
That is, I don't see why the patch (or patch variant) would require us to change 
symbol versions.

Yes, backporting would be good. Essentially Gnulib is already doing that, for 
Gnulib-using apps.
