NW74 authority check on call transaction

Hello,

On NW74, ABAP help mentions that usage of CALL TRANSACTION statement without the new additions WITH AUTHORITY-CHECK or WITHOUT AUTHORITY-CHECK is obsolete; And among other things, these additions override the content of TCDCOUPLES.

Does that mean maintenance of calling-called tcode pairs in SE97/TCDCOUPLES beyond NW731 is not longer necessary?

I actually ran a test for SM21 that calls SM21_OLD, when the SM21-->SM21_OLD check in SE97 is disabled, the auth.check for SM21_OLD still takes place and shows in trace too!

And is it correct to infer that MM-- tcodes calling MM01 mean MM01 will need to be added to the relevant security roles?

I've searched forum for relevant posts/blogs, could not find any close hits on this find. Please share your thoughts, and if you found a way to still enforce such checks.

Thanks,

Pawan.
