Is this really needed in a manpage, though ? AFAIK manpages are ASCII document created with any variation of troff/nroff/groff and piped into less -s. There is no need for any semantical distinction if display is the same, since the best interaction you can have is searching for something.
While I like the venerable look they have, those books aren't what you use daily to document yourself on how your machine works. I was speaking about those manpages we use when we don't know what the letters are for in the itemized output of rsync, for instance.

But you can create pretty hard-copy versions of the manpages on your system with groff, the same way these books were created with troff (which groff is a replacement for.)
