Excel - .xls vs .xlsx

Is it on the roadmap for mendix to support the .xlsx (OOXML) format in future? If so when. Just curious I see it already uses Apache POI - HSSF. I will just import the XSSF libraries myself to accomplish what I need, just wondering when Mendix will natively support the new OOXML format?

It's not on the roadmap at the moment, considering there are so many people still using old excel versions that can't use the new format.
