macOS already provides a similar set up, but it's barely configurable.
For example:

breton:/Users/alan>/usr/libexec/path_helper
PATH="/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/alan/.local/bin";
export PATH;

It builds the path from /etc/paths and the files in /etc/paths.d, and
anything else that's already in the environment.

It insists on setting its own order, though. It's a massive pain, but
that's how all the shells on macOS build their initial $PATH.
