I have updated A-Bind-Pose (in my first post).
The latest version is more precisely matches RL Bind pose generated on export. Although it is still not 100%.
I'll open another FT ticket. I believe we should have an easy button to put character into base T and Bind A poses in CC
Also do not forget to Skin Weight in A-Bind pose whenever is possible if you intent to export an avatar and work with it outside of CC.
