Yes.

The only issue is that this was only added to mode-line-format in Emacs

No, that's not an issue, or rather your solution isn't the way to solve it.
In trunk Eglot use everything that is in trunk Emacs. In released Eglot
versions name sure you depend on capable versions of core GNU Elpa
packages, a set which already includes project.el. So basically version
bumps solves it.

So please show an updated patch, and don't forget the etc/EGLOT-NEWS entry.
