No inside information, but in those days we did have @davidfor (R.I.P.) which was almost as good. See this post from 2020.

Yes indeed. Every reading app (eink, Android etc) may have its own widows/orphans "solution". One-size-fits-all is pretty rare for anything CSS-related in my experience.

Personally I don't keep any widows/orphans CSS at all in my calibre master epubs. I auto-apply whatever is needed (if anything) during my send-to-device process.

Tedious observation by paging through an epub, after having removed the config settings. A 3-line paragraph was never split across pages. A 4-line paragraph (if split at all) was only ever split 2 and 2.

And: the kobo config file settings only overrides the <body> orphans/widows settings.
Yes, except for item 1 (kobo hardcoded defaults), because I don't know what you mean by it.
