Nozzle change - calibration?

Currently I run calibration on my P1S each time I change the nozzle(complete hotend) from Bambu 0,4 to 0,2 or 0,6 - taking about 26min

I understand it might help to early detect an incorrectly plugged connector.

Beside this:
What are the benefits ?
Is it really significant for print quality or complete nonsense to do each time ?
Is there any fast-path ?

Thanks in advance
