With this I disagree (not with the feasibility, but with
it being good software design). It means that in order to
reproduce a document, you have to distribute the metrics
as well. It also means that automatic kerning is restricted
to the glyphs of a single font. These were the main reasons
why I introduced the ".kernpair" request in Heirloom troff.
