It may provide just as good a base for actual experiments as specifying 
any other temperature; I guess the systematic error introduced by a 
deviating temperature is comparatively easy to "compute away", and I 
also guess that it might be easier to measure an actual temperature than 
to achieve a certain reference temperature, so the math to compensate 
for the deviating temperature might be needed anyway, making 0K just as 
good as any other reference temperature (maybe making the math even 
slightly easier).
