I think you're overestimating the amount of care and typographical
knowledge that your average kernel developer has. Most of these
UTF-8 characters come from latex conversions and really aren't
necessary (and are being used incorrectly).
You seem quite knowedgeable about the various differences. Perhaps
you'd be willing to write a document for Documentation/doc-guide/
that provides guidance for when to use which kinds of horizontal
line? https://www.punctuationmatters.com/hyphen-dash-n-dash-and-m-dash/
talks about it in the context of publications, but I think we need
something more suited to our needs for kernel documentation.
