I do not get lowercase greek letters on the itemize as should happen with symbol setup g.
A minimal example, showing the demise of lowercase greek against succes for uppercase.

\starttext
\startitemize[g]
\startitem nr 1\stopitem
\startitem nr 2\stopitem
\startitem nr 3\stopitem
\startitem nr 4\stopitem
\stopitemize
\startitemize[G]
\startitem nr 1\stopitem
\startitem nr 2\stopitem
\startitem nr 3\stopitem
\startitem nr 4\stopitem
\stopitemize
\stoptext
