I have attached a simple solution that solves this specific problem. I'll
push it if it looks like an OK solution for you.

Apparently, there is more to the code than I initially understood. I agree
with you, I no longer think we should change anything here on the short
term.
However, I think it behaves strange:
For example (on a Linux machine):
env EMACSPATH=::/home::/bar:: emacs -q --batch --eval '(print
exec-path)'
("/usr/lib/lightdm/lightdm" "/usr/local/sbin" "/usr/local/bin"
"/use/sbin" "/usr/bin" "/sbin" "/bin" "/usr/games" "." "." "/home" "." "."
"/bar" "." ".")
Here, I don't think the ".":s should be included.
Another example (again on Linux):
env EMACSLOADPATH=::/home::/bar:: emacs -q --batch --eval '(print
load-path)'
The result is too long to print, as it duplicates the standard load
path five times.
Here, wouldn't it suffice to add the default load path once?
