Smaller binary diffs are nice for a number of reasons. Let's tell people
about them!

+Smaller Binary Differences
+--------------------------
+Having reproducible builds means that only changes in source code or
+build environment (such as the compiler version) will lead to
+differences in the generated binaries. This minimizes the changes in
+artifacts which reduces storage requirements and network traffic for
+delta updates.
+
+With similar artifacts, testing can focus on parts that changed while
+still preserving confidence about unchanged code. This can speed up
+quality assurance and development speed.
