something numbers=oldstyle could be supported but i see no real
reason
for it since then we end up in endless lists of possibilities
(given all
kind of combinations)
I have not yet played with Lua, thus I can't follow your and Mojca's
discussion at that point.
But to have a handy way to switch on/off oldstyle figures would be
very useful!
"numbers=oldstyle" shouldn't be considered as a theoretical
possibility, it is needed quite often.

The following should work, can't test it at the moment
\definefontfeature[enableoldstyle][onum=yes]
\definefontfeature[disableoldstyle][onum=no]
\starttext
123 \setfontfeature{enableoldstyle} 456 \setfontfeature
{disableoldstyle} 789
\stoptext
you mean typeset with Lua, right? with XeTeX it yields
! Undefined control sequence.
l.20 \setfontfeature!
This is a new feature introduced only for LuaTeX, not XeTeX
and allows you to choose a different fontfeature in your document.

Could be used overwrite the defaults for \os and \sc.

\def\os{\setfonrfeature{oldstyle}}
\def\sc{\setfonrfeature{smallscaps}}
