That is one definite advantage of the Polemaster method, the first steps are to establish the mechanical axis of the mount. I have not tried any other ways than that apart from dead reckoning (Degrees off) and drift aligning via PHD2 and a guide cam.
I still think that drift alignment has the potential to be more accurate than the Polemaster, but if it can reliably get you to a "close enough for government work" situation in ten minutes then what is the point?
While it would also render imaging more or less impossible, the wind I suffered under on Saturday night when testing would make drift alignment with the guider pretty hit and miss. You would need to drift for a long time on each iteration to be sure of the trend line reflecting the PA error, not wind buffeting the gear around.
