SSH1 vs. SSH2 - compression level

I was searching for this information virtually everywhere, but as I 
couldn't find it - I'm asking here.

I was wondering, why setting the Compression Level was removed in SSH2, 
and if on, is always set to 6.

In SSH1 it was possible to set the Compression Level from 1 to 9.

I have made some tests with Compression Levels using scp: SSH1, 
compression 9 (highest available for SSH1), vs. SSH2, compression 6 (the 
only available for SSH2), and, no wonder, SSH1 *always* won, no matter 
if it was tar'red /etc (lots of txt files), a long pdf file, or even 
long avi file.

Why not let the user what best suits him?

Or maybe there is some way to turn it on in SSH2?
