I see at least 2:

 1) The default is always the same, no matter how the package was
    configured.  IOW, no need to remember or even care about the
    options passed to the configure script, in order to know what will
    happen by default with compression.

 2) Not introducing yet another obscure option to configure, which
    already has too many of them.

Perhaps you never produced more than one installation from the same
source tree.  I do it all the time: sometimes I install on the same
machine, sometimes for copying the installation to another.  The
end-user system frequently needs different options, because the needs
of the end users are different.

What do you mean by "recreate an identical configuration"?

Yes, all 75 of them.

Those few that care will find it out once, and then remember it, like
they remember this new option to configure.
