Otared points out that the distinction between \triangle and
\bigtriangleup comes from plain TeX. plain.tex has these definitions:
\mathchardef\triangle="0234
\mathchardef\bigtriangleup="2234
So \triangle is a math ord and \bigtriangleup a math bin.
For compatibility, that should probably stay true in ConTeXt too---even
the low placement of \bigtriangledown, which I don't understand but
which does reproduce plain TeX's placement.

Hm, like different dialects of a language. Plain TeX definitely speaks
a pure-mathematician dialect. It would be interesting to see what
symbol groups are useful in other dialects.
