So, I propose:
reduce install time
reduce image size
reduce compose time

+1 Sounds very reasonable.

Exactly what Kamil wrote. Few percent grow is negligible, but install time
reduction is huge.

The areas where hundreds of installations are performed from an image are
hardly the common case, and those installations should really consider
composing their own images with exactly the package set that they need
(including site packages that Fedora cannot ship), images which they can
then compress with a faster-to-decompress algorithm. I think that we should
optimize for the standard user who installs exactly once.

It is pretty common for us in Fedora QA (well, I'm quite biased in this case).
And no, we cannot compose our images, we have to test the exact same
images that will be shipped. We cannot test custom images and pretend
the results are going to be the same for official images.

And finally, those few percent can make the difference between fitting on a
given fixed-size physical media or not. The original change proposal of
trying to minimize the size might actually make at least the smaller spins
fit on a DVD again.

All current Fedora spins [1] are well within the DVD size limit (4.7GB), even if 
the images grow a few percent. This is also true for optical boot release
blocking images [2][3][4].
