I think these patches are nice-to-have optimizations and refactorings to
make code look better. They are not necessary for the main feature. They
don't fix any bugs. But they were requested in the thread, and make sense
in my opinion.

I really don't know what's the policy of applying code improvements other
than bugfixes post feature-freeze. IMO they are safe to be appiled to v17,
but they also could be added later.
