Pardon the pun in the title. The problem: emacs-all-the-icons has a subdirectory fonts, that it wants installed to share/fonts (currently, they are installed to its own fonts directory). Some of them are vendored, but at least one seems to be genuinely their own.
Proposed solution: Make it, so that emacs-all-the-icons installs its own fonts to share/data and copies vendored fonts from inputs where packages can be found. Note, that this won't work for a setup with all-the-icons in a non- default profile or ad-hoc environment (compare #31403). Would everyone be fine with the proposed solution or is there a better one?
