SAP BW Modeling tools not only for HANA ?

Hi Guys,

Today I have noticed that I can on my NPL instance (https://blogs.sap.com/2017/09/04/sap-as-abap-751-sp02-developer-edition-to-download/) run eclipse SAP BW modeling tools. Until today I was thinking that this tools are reserved only for hana based system. Is there any official info for supporting other databases ? This is not working 100% good, but I can display some objects or even crate some restricted in this version (like Composite Provider).

Eclipse Version: 2018-12 M2 (4.10.0M2)

Modeling Tools for SAP BW/4HANA and SAP BW powered by SAP HANA Version: 1.19.24
