I can confirm. My workaround which predates the stylealternative
mechanism also stopped working, so there must be an issue on the level
of font feature selection.
\definefontfeature [math-text] [math-text] [ss04=yes]
\definefontfeature [math-script] [math-script] [ss04=yes]
\definefontfeature [math-scriptscript] [math-scriptscript] [ss04=yes]
\setupbodyfont[lucidaot]
\starttext
\startTEXpage[offset=3bp]
$\mathcal A$
\stopTEXpage
\stoptext
that is a nasty one ... in font-fil.mkvi : we cannot use an edef as that
makes features get lost
\def\font_basics_get_font_parameter_nop#key=#value,%
{\if]#key%
\font_basics_get_font_parameter_nop_finish
\else
\expandafter\normaldef\csname p_#key\endcsname{#value}% % no edef
as we need to keep \mathsizesuffix
\expandafter\font_basics_get_font_parameter_nop
\fi}
\def\font_basics_get_font_parameter_yes#key=#value,%
{\if]#key%
\font_basics_get_font_parameter_yes_finish
\else
\expandafter\normaldef\csname p_#key\endcsname{#value}% % no edef
as we need to keep \mathsizesuffix
\expandafter\font_basics_get_font_parameter_yes
\fi}
but even then, the official way to trigger such features is
\setupmathematics[stylealternative=calligraphic]
