> It just works.

Until you want to like, use GitHub.

There is a clean bifurcation between just works and Microsoft compatible.

i don't like how these companies dictate standards. It's always the case, but they do spend a great deal of money making sure practices morph into standards.

they figured out the "de facto standard" game...

for example:

Microsoft Word DOC. Due to the market dominance of Word, it is supported by all office applications that intend to compete with it, typically by reverse engineering the undocumented file format. Microsoft has repeatedly internally changed the file specification between versions of Word to suit their own needs, while continuing to reuse the same file extension identifier for different versions.

Whoa! Did you see where those goalposts went?

Presumably, they were working before Microsoft came up and they needed to be embraced, extended and extinguished.

Your goalpost already moved from "IPv6 just works" to "IPv6-only just works" though. ;)

In all seriousness, I have IPv6 enabled and GitHub works just fine for me. Though at a slower speed sometimes because the IPv4 CGNAT is heavily congested in my area.

If you count that as IPv6 just working, sure.
