One feature request from business that caught me by surprise when recently implementing an editing page was that it should discard all font styling when pasting from Word. That is the #1 feature missing from all rich text editors: ability to restrict allowed formatting. No user specified fonts, no user specified font-size (all headings must be paragraph style), all lists must use standard style, etc... This is where Markdown/CommonMark shines: no hidden formatting that is difficult to get rid of. The real problem with Markdown is it lackluster support for tables and support for site-specific macros.
