Is nobody interested in this? I don’t see any problems with the patch.
This must have been of concern at least once, judging by fonts-dir-file’s existence. The fontpath mechanism is the only way today to make the core (server-side) fonts work reasonably.

> This should produce a "share/fontpath.d" directory in the profile which is a font catalogue as described in Xserver(1). Then the X server font path can be set to include this catalogue and it will find the installed fonts. This concerns all legacy X11 applications using the core fonts system, and most importantly xterm.

> The hook ‘fonts-dir-file’ was originally added for this purpose as the comments can tell; you would include e. g. "share/fonts/X11/misc" from the profile in the font path, which is a union directory with symbolic links to fonts that want to install there and a fonts.dir file describing all of them. This has not been working for ages, since the X.org server stopped following symbolic links to font files for security reasons. It should be removed.
