@h5e I have a slightly more nuanced take:

99% of the time what people want is the stuff implemented by markdown. That is, bold stays bold, italic stays italic, bullets stay bullets, but font size and styling goes away. That's the real problem - if I copy text in 30 pt Comic Sans, I don't want that. But if I copy a list of bullet points, I want them to stay bullet points.

Also, when I do copy with style/format, it should reproduce perfectly. But html is a trash language. So we get mangled.
