Why recently updated FP-ATR-LTE1 is not aligned to X-CUBE-CELLULAR 5.x project?

[PGell.1]

I'm thinking to design a Sensor-Cell to Mqtt cloud demo. But a few days ago I discovered ST FP-ATR-LTE1 package that also is using BG96 modem on the same Disco L496 board. This is the same board supported by X-CUBE-CELLULAR, and it provides an Asset Tracker demo with ST-DASHBOARD web. FP-ATR-LTE1 package has been updated recently on Feb.2021 period. But it seems to me based on older X-CUBE-CELLULAR 3.x package architecture.

Is this true, any reason ? Does have X-CUBE-CELLULAR a roadmap for further releases?
