Now try to link it with Emacs, enjoy the pages of linker errors, and get
frustrated two weeks later when the Skia developers change the signature
of some basic function causing the program to not work anymore.

That's been my experience working with Skia, and I think other people
will agree as well.

I would really appreciate names.

Alternatively, we could also ask RIF->draw_window_divider (which already
exists in every graphical port) to draw a line there.

It's just that nobody has put in the work to make that happen.
