These aren't in opposition: it's what I meant by "on-boarding".
If remacs didn't exist the hypothetical developer wouldn't be contributing to full Emacs (it never crossed their mind, or it's too intimidating, or whatever other reason), but through their work on remacs, they've also contributed to the original emacs. The point is that the latter contribution would never have happened without remacs.
