Bi-Directional contact printers are the "workhorse" at many of the medium and smaller sized laboratories:

I agree with you that the 0.005 inch vertical shift when printing BH-1866 original onto KS-1870 print film in both directions is an issue, especially for two-strip 3D. Of course, the printers can still be consistently used in the head-to-tail mode with a rewind step for the printing original(s). Contact printers can be very steady --- I have even seen some well-maintained printers do a reasonable job combining separation exposures (obviously printing R+G+B in the same direction).

That of course begs the question as to what they do at the biggest labs. Loop the negatives through Disney-style roller cabinets?
