indeed setups is the way to go

\enablelanguagesetups is somewhat tricky as we then also want to disable 
them selectively which boils down to either tagging them all internally 
or let lua deal with sets in which case we need some optimization to 
prevent redundant calls

also, we need the reverse actions then i.e. for german we want to 
disable the punctuation

\startsetups [fr] [punctuation:reset]

\resetcharacterspacing

\stopsetups

and for style changes that's quite some extra code (and adding an extra 
level of language hashes to each mechanism is also no solution)

so, we might distinguish between 'mainlanguage' and local 'language'

\startlanguagesetups [fr:punctuation:set] % local language
   \setcharacterspacing[frenchpunctuation]
\stopsetups

\startlanguagesetups [fr:punctuation:reset] % local language
   \resetcharacterspacing
\stopsetups

\startlanguagesetups [fr:itemize] % mainlanguage
   \setupitemize[symbol=2]
\stopsetups

or so ... needs bit of thinking
