There are, but context is looking for the wring character; it is looking
for U+3014 (which I think is a CJK bracket and does not look like
\lgroup either) while it should be looking for U+27EE (whose Unicode
annotation precisely says "lgroup"):
\setupbodyfont[xits]
\starttext
$$\bigg\lgroup\dots\bigg\rgroup$$
\def\lgroup{\Udelimiter "4 "0 "27EE}
\def\rgroup{\Udelimiter "4 "0 "27EF}
$$\bigg\lgroup\dots\bigg\rgroup$$
\stoptext
It was not extensible though, the version in git now grow, but starts
with a relatively large size, check and tell me if it should be smaller.
