This is a "feature" of \mathop.

\definemathcommand [D] [nolop] {\mfunction{D}}
\starttext
Compare $\D f$ with $\mfunction{D}f$ and $\mathop{\mfunction{D}}f$.
\stoptext

If the argument of \mathop is a single character, \mathop centers the 
glyph on the math axis (This is useful for \sum, \int, \prod, etc.). To 
circumvent this, use:

\definemathcommand [D] [nolop] {\mfunction{D}\kern\zeropoint}
