+Somehow related, i just did some rpm size comparisons for thunderbird
+-l10n packages, to see what can be gained if we switch them back to
+uncompressing the (zipped) .xpi files and so let them profit from
+rpm binary payload compression. It's not much for a single package,
+but overall it's a reduction by 35%.
+
+Maybe this is a viable solution for other packages too, which currently
+carry files which are already compressed when building.
+
+Some numbers (total size of-l10n packages, followed by time output for
+the build to see the cost of this switch)
+
