Can we root M using the same Chainfire script we did on L?

I just flashed my way up to M from the Fi-specific L, using the M image from the developers site. I was rooted, but using stock recovery. Everything went fine. So I'm stock, unrooted on M now.

Now I want to root again, (keeping stock recovery), and before I do, I want to be sure Cainfire's original N6 root for L, is still going to work right on M?
