"An li element's end tag may be omitted if the li element is immediately followed by another li element or if there is no more content in the parent element."

I know that makes sense, but it feels unsettling and wrong. Where are the good old times of proper XHTML.

  They've been superseeded by the even older and better times of SGML ;)

  HTML and XHTML are different things, and you can have proper documents in either. HTML is a subset of SGML. XML is designed for machines to read and write. SGML, humans. It's like the difference between JSON and Markdown. (Addendum: TIL HTML5 is not parseable as SGML. Because, reasons.)

    According to Firefox, chrome and amusingly not IEs xmlserializers, xhtml tags are case insensitive. The scars oh the scars..:

      If you send XHTML with the XHTML MIME type, the tags are case-sensitive. If you send it as "text/html"... well, then presumably you're relying on XHTML 1.0 Appendix C and letting browsers parse your XHTML as HTML. And HTML is case-insensitive.
