Indeed. E.g. I just compiled Qt and package size went down from 34 MB to 25 
MB. This saves me about 10 MByte upload for each arch. I didn't note any 
massive increase in compression time compared to compile and upload time.

Sure there are edge cases like big icon packs which wont compress well anyway. 
But in general the benefit of the way smaller packages is rally worth it. And 
you don't have to forget that you only compress a package once; but it's 
uploaded and downloaded many, many times.
