The reason is that some big cloud guys need it as a tgz because that is
what they use.

It is just as easy for anyone else (not specifically needing tgz) to
extract the image to obtain a raw file from tgz format as from gz
format.  (one command, you end up with the raw file).

This way, we only need one compressed raw image file, not 2 or 3 raw
images compressed in different ways.

Thanks,
