No, you don't have to, because oldstyle is predefined in type-ini.tex,
two other predefined fontfeatures are "default" and "smallcaps" :-)

\definefontfeature[onum][onum=yes]
\definefontfeature[lnum][lnum=yes]
\definefontfeature[tnum][tnum=yes,onum=yes]
\definefontfeature[pnum][pnum=yes]

\starttext

\setfontfeature{onum}123456789\par
\setfontfeature{lnum}123456789\par
\setfontfeature{tnum}123456789\par
\setfontfeature{pnum}123456789\par

\stoptext
