Sorry, but I strongly disagree here. You cannot call such a file
"platform-independent". This goes completely against the spirit of the
FHS, and against the Unix way of doing things. Will you tell me how, in
a real-world configuration, you're going to automate cache generation on
a /usr/share directory shared between several platforms?
This approach is perfectly suitable for the user-generated file in
$HOME, but it isn't acceptable for the system directories. Even the
fonts.cache-1 approach is quite questionable, as you always end up with
stale cache files not registered by the packaging system and never
removed.
