xorg-mkfontscale.script should not delete empty fonts.dir because this file is needed in a directory to be accepted as a font path by xorg-server. A directory with no fonts is useful to create a custom fonts.alias for fonts installed elsewhere and avoid conflicts with other fonts.alias files provided by system packages (e.g. /usr/share/fonts/misc/fonts.alias provided by extra/xorg-fonts-alias-misc). A fonts.alias file in one font path can define aliases for fonts located in any other font paths.

xorg-mkfontscale.script source code:
find "$d"fonts.{scale,dir} -maxdepth 0 -size -3c -delete

xorg-server source code:
* xf86ValidateFontPath --
* Validates the user-specified font path. Each element that
* begins with a '/' is checked to make sure the directory exists.
* If the directory exists, the existence of a file named 'fonts.dir'
* is checked. If either check fails, an error is printed and the
* element is removed from the font path.

mkfontdir manual:
The file "fonts.alias", which can be put in any directory of the font-path, is used to map new names to existing fonts, and should be edited by hand.

Section "Files"
FontPath "/usr/share/fonts/custom"

terminus -xos4-terminus-medium-r-normal--16-160-72-72-c-80-iso10646-1

The directory /usr/share/fonts/custom is not added to font paths because xorg-mkfontscale.script deletes his empty fonts.dir file.

Shouldn't you pick a folder outside of /usr/share/fonts for unpackaged files, like in /usr/local/share/fonts?

Well, it is a packaged file. All my config is a package.
Beside, using /usr/share/fonts can leverage the auto upate mechanism instead of manually executing mkfontdir on /usr/local/share/fonts.
