My understanding is that the criteria has remained the same but the charging minimum voltage has been increased to prevent the battery going into shutdown mode.
I don't believe that's a correct interpretation. Quite the reverse.
If Li cells are discharged too far you cannot safely recharge them. The charging minimum voltage is the voltage at which it goes into shutdown to prevent charging.
If you raise that voltage limit you make the battery safer but you increase the number of batteries that will shutdown due to over discharge.
