It’s probably a call to make commerical launching easier - with less potential of defects on specific situations - while network is unloaded.

Not launched commercially yet.
I have to make explicit that I experience NSA as a customer only.
Not many insights.
I mostly involved with SA only.
Even for FDD used in 5G low band massive MIMO solution, used with single beam only, i.e. it’s purely SU-MIMO or MU-MIMO.
Invention of massive MIMO concept started with tm8 mode in LTE.
Earlier it’s like 8T8R antenna used for trial to test tm8 gain, in comparison with tm7, tm3.
Then massive MIMO concept come into picture with increased layer concept so mu-mimo taken birth
Need to be mentioned: Commscope antenna used in field which is 8T8R.
