the issue is that we have definechemical doing something different
(compatibility) but we can do this:
in chem-str.mkiv:
% \installsimplecommandhandler \??chemical {chemical} \??chemical % no
\define...
\installcommandhandler \??chemical {chemical} \??chemical % no \define...
\let\setupchemicals \setupchemical
\let\definechemicals\definechemical
then we can do:
\starttext
\definechemicals[foo][axis=on]
\startchemical[foo]
\chemical[SIX,ROT2,B,R6,SUB1,FIVE,ROT1,B][1]
\stopchemical
\stoptext
