And then every so often mailman hits you up with "I'm receiving all these bounces from your email server!" because all the various garbage anti-spam techniques were not quite thought out with mailing lists in mind or people have lots of misconfigured servers and servers with different acceptance criteria, and it's all a big mess.

Configuring git send-email is only half the battle, anyway - chances are you want to participate in the discussion of your patch, so better figure out how to make sure your email client will not send the forbidden HTML email.

That's a battle??

This sounds like hyperbolic brought on by dislike, not a real indicator of time cost/effort. You've already spent more time complaining, than the work done to do these things!
