When my mouse starts blinking I just plug cable and continue whatever I'm doing and it's a solved problem. No second guessing if I can take a break now in the middle of a meeting, no unnecessary cognitive load, no need to remember to charge it when "I have the time", it's... magical.
Personally I don't find it to be a particularly huge "cognitive load" to see a "mouse battery is low, charge soon" notification and then just charge it at the end of the day.
But for those that do, it's great that we have choices.

It just works.
