My pet peeve is Python specifically. They have a PEP per release which basically tells you what all will become EOL on this release, which is very confusing.

And they also list unsupported releases on the main download page.

Can you clarify on the “release cell” part? Not sure what you mean by that.

I get you on the Windows part. It took me quite some time to figure out what all is even possible. The Windows page definitely needs a disclaimer.
