Implicit would be nice, it's not actually a hard requirement.

We must not rely on system-installed files outside the source tree,
build tree or outside the toolchain.

Please provide a patch removing any ln to files under /usr/share, etc.
The explicit rules add a rule to download the Unicode.txt file into the
src tree.  That's the only file we may rely on.  If it doesn't exist,
an implicit rule should not break the build.
