@ag Hmm, no dice.

If I open -a /usr/local/Cellar/emacs-plus/25.1/Emacs.app/Contents/MacOS/Emacs

I still don’t have binaries from my host system, available to emacs’ path or exec-path.

The version is _*GNU Emacs 25.1.1 (x86_64-apple-darwin16.3.0, NS appkit-1504.76 Version 10.12.2 (Build 16C67)) of 2017-02-05*_.
