SSCI at EDI now wants passport..

This must be a new change... is it VS alone? EDI alone?
Went to SSCI machine this morning, before an EDI-LHR (no onward connection) and the first thing the machine asks for is your passport.. With no option to skip/cancel/alternative.
Previously it asked for your booking reference and/or credit card.
Result was queueing for manned check-in desk, despite having hand luggage only.
Will print at home next time, obviously, but surely this is an odd move by whoever is responsible?
