I think, this is a deliberate choice (see texinfo manual): either merge
or overwrite.

I tried looking into this, but I am simply not familiar enough with
Emacs' startup. It seems to me, that this mechanism would not work
without additional, heavier changes to nsterm.m, unless you are ruling
out users moving their application bundle (bad idea, in my
opinion). While I do consider setting paths within a program via
environment variables "unexpected", the other variables have not been
problematic for me, so far. As far as I can tell, w32 uses a similar
approach (w32.c init_environment), and only excludes INFOPATH.
