I agree that 6.3 has become the new 5.6 and don't like that trend. Just my $.02

And that is because ?

Obviously less available light to use (also for the autofocus), requiring higher ISO or lower shutter speeds (not always possible) and more DOF.

Also, on cameras with high pixel densities (Z7, Z50), f/6.3 means the maximum achievable resolution is already diffraction limited.
