OpengGL: Get MAX_VERTEX_UNIFORM_VECTORS returns NULL

Lime legacy:
Is there a reason why glGet() parameters GL_MAX_VERTEX_UNIFORM_VECTORS and GL_MAX_FRAGMENT_UNIFORM_VECTORS are defined in openfl.gl.GL, but return null?
I saw in OGLExport.cpp that those parameters are commented on the switch statement, and I guess they end up as being considered strings instead of ints, but maybe there was a reason to ignore them.
