It would be also useful to change the following line in font-pre.mkiv to use 
\setcharacterchasing instead of \WORD (won’t work anymore when you remove 
\groupedcommand from the \WORD as written in the comments in typo-cap.mkiv)

\definealternativestyle [\v!WORD]           [\WORD]        [\WORD]

Additional entries for \word, Words etc. in font-pre.mkvi are useful as well 
because “style=word” looks better than “style={\setcharacterchasing[word]}”.
