I agree, there are very good reasons.
One of which is a lack of any sort of commercial pressure on the design and
provision of space life support systems.
I posit that much better designs can be had, one we get away from the
current 'stunt' attitude towards the exploitation of space and into a more
economic commercial exploitation.
With attendant competition and subsequent pressure on price and performance,
rather than 'we done it this way before, so we are going to do it this way
forever' paradigm

Like I said: "There are ways of dealing with this, but it adds serious
complications." There are reasons why you *don't* see spinning separators
in existing space life-support gear.
