CQL2-TEXT parsing known issues

[captaincoordinates]

Is it possible to build a list of known issues for CQL2-TEXT parsing?

• [cql2-text] NOT operator is not supported #68 identifies a problem with NOT
• My testing indicates that T_INTERSECTS does not work as expected.

#22 is closed as completed, though it's not clear to me if it refers to CQL-TEXT or CQL2-TEXT.

Does anyone know the state of CQL2-TEXT parsing, or do we need to extend the tests to understand the current state of the parser? If known issues were documented it would help any project using pygeofilter as it could point to this list when documenting issues with filter support.
