Thanks everyone for a strong discussion, My conclusion so fur as we wait for more views is that we shall first get rid of spa-module for this release and create a gap for MFE ,then we can include it in the coming release of Ref-app 2.12 as suggested above by @jdick @burke
. @burke i think we do have time to discuss about it ,we can still hold on with it to have fully conclusive decision
Let me know if this is the final conclusion on this. thanks
