A valid question.

I can understand and very much appreciate [1/4] as a very focused fix to the problem. Very small part of this step, namely, make the DC_SHA1 the default everywhere, is also very much welcome.

Everything else I see in these patches are extra "while we are at it" that should not exist. These "while at it" changes tend to somehow implement more subjective choices that will cause more discussion and take more review resources. Not all "white at it" may be more subjective, but at least in this series, they appear to be.

They distract us from the core changes and slows us down. It is OK to do them as totally unrelated clean-up changes long after the dust settles, but not entangled with the other more important changes like these patches.

Thanks.
