Good catch. There are likely other things that are similarly missing. Unfortunately, I haven't been able to put together a comprehensive way to verify everything.
The Python API is based on the C++ API (wrapped with SWIG). The C++ API is really everything in src/geom_api/VSP_Geom_API.h.
The AngelScript API is registered through src/geom/ScriptMgr.cpp.
These are manually maintained, so we're lucky that there aren't more places where they diverge.
It'll be fixed in the next release. If you need it sooner, I can make a patch available on GitHub.
