+# NOTE: Generally, we do not want packaging to be so dynamic
+#         (eg: `date` as 'pkgver', or building from a git branch tip),
+#         such that the package version or contents is inherently not reproducible.
+#       In the case of pure meta-packages like this one though (and package-groups),
+#         reproducibility reduces to that of it's dependencies; and neither
+#         meta-packages nor package-groups should play a role in any dependency chain,
+#         other than the mandatory ones (currently only 'base').
+#       This dynamic approach is far easier to maintain than an explicit white-list,
+#         which is a highly desirable property; becasue the use-case for installing
+#         1GB of fonts, seems too small to justify maintenance of this package at all.
