I think it depends.  We had a feasibility study for a mid size  
concert hall done about 5 years ago.  I requested a climate  
controlled closet for pianos.  The architect claimed he'd built lots  
of performance venues and made the claim that "most" places preferred  
to have the piano be at whatever the hall climate was.  I think once  
you turn on the hot lights, it really doesn't matter.

Our pianos stay on stage in our small recital hall, even though we  
have closets designed and included specifically for the pianos.  I  
know I've seen changes in our piano just from turning on the "house"  
lights during the day, and the change is significant enough that I  
changed my tuning time from first thing in the morning to just before  
recitals begin.  I suspect you are more likely to  have a temperature  
change than much of a humidity difference, and the piano will react  
almost immediately to temperature.  So I don't see how you can get  
around some degree of instability either way.
