Very important, cause the 12 speed, the narrow wide technology on cassette the 100% fit-alignment becomes more important.
With 10 or 11 speed, bigger space between cogs and no narrow-wide cassette and more wide chains you have more margins.
New setup axs aks 100% alignment. It's not so difficult to make this. Good news is for xx1 and x0 there's sometging. But for my sram red road bike and gx axs for my mtb it isn't available yet.
