Disagree. The name plainly says "CD", nobody should re-define plain 
English words. Even more: by continuity, this always was meant for 
burning CDs. The size of image exceeding standard restrictions is really 
annoying, and ideally should not be tolerated as "released" by self 
respected organization.

This is just my opinion. I as person attempt to apply this to what I do.
