No <head>, no <body>, no problem?

I was surprised today when I discovered that the HTML response from https://twitter.com does not include a <head> tag (or <body> for that matter), though does include tags (e.g. <meta charset>) that are only valid as children of <head>.

Today I learned that this is ok.

Per the HTML spec:

A head element's start tag can be omitted if the element is empty, or if the first thing inside the head element is an element.

A head element's end tag can be omitted if the head element is not immediately followed by ASCII whitespace or a comment.

Similar applies to <html> and <body>, see: https://html.spec.whatwg.org/multipage/syntax.html#syntax-tag-omission

This Google HTML/CSS Style Guide even recommends omitting all optional tags.
