To you perhaps. An improved binary infoset removing yet more redundant 
information by itself will be likely to generate less compressible data, and the 
ratio matters in cost/benefit analysis.

If I have (completely arbitrary numbers):
   bix            10k
   bix+gz          8k
   better-bix    8.5k
   better-bix+gz 7.8k

Then even though the last one is the smallest, option 3 will be de-encoded a 
*lot* faster. At some point the different between a compressed binfoset and an 
uncompressed one becomes too marginal to be interesting.
