I just use git, I don't have the deep technical understanding of its
implementation as you may have. From my perspective I can't think of
how this breaks backward compatibility, or perhaps your definition of
backward compatibility does not align with mine.

And please don't over generalize and misconvey what I said. I am not
saying more information is always good. Did you not read anything I
wrote?

Also good branch names may help but that doesn't go into detail and
explain features that may have been sitting on a topic branch for
weeks. That's not a practical solution to the problem. Also branch
names do not determine or influence the skill and quality of a
developer, as you seem to imply.

I'll do us both a favor and end the discussion here, as I do not feel
you are being very patient or welcoming in the discussion. I sense
frustration on your side.

You mean you don't want to? That's fine, if you don't have the will or
patience to explain then I won't bother caring.

First of all, you keep calling this an argument. Perhaps it is for
you, since you're being absurdly rude with me and impatient with the
discussion. This is a brainstorming session. My suggestions may not
seem rational or make sense, but this is natural since I am ignorant
of the finer details of the application.

You're really just overanalyzing my statements from a nonsensical
perspective. I am talking about not adding more settings to an already
complex set of settings. I am not justifying my feature. I think the
feature is just as justified as everything else. Git is FULL of tons
of little options to cater to niche workflows.

I am not fighting against having another option. In fact, that was my
idea to begin with. I am investigating and trying to discuss all
possible approaches and perspectives.

Your attitude is not very welcoming to those that wish to contribute
to the project. In fact, because of your attitude towards me, I will
kindly see myself out. I do not have time to spend my free time
dealing with this nonsense and irrational rudeness on a mailing list.

Thanks to Heiko and others that were more welcoming and kind.
