Maybe because they actually /do/ render identically, provided you 
specify "#version 3.6" to enforce backward compatibility?

Things only get complicated when you explicitly use a flexible-gamma 
file format (such as .png or .hdr). Having these render identically as 
well would probably require different "#version 3.6" defaults for the 
parameters of 3.7's gamma-handling mechanism. Or a nasty hack of that 
mechanism.
