No, I'm definitely not wanting to imply that.  :-)  SDV() is 
preferred inside of cookbook recipes and the like; I find it to
be much less useful in local customization files.  In the 015909.html
article mentioned above, I suggested SDV because the admin wanted
the farm config to be able to override the local/config.php file,
but I think this is somewhat rare.

Essentially I think of the SDV() function as deferring to the
wishes of other scripts or recipes; while an assignment statement
is more forceful.  Thus, the statement

    SDV($Var, 'XYZ');

says "I'd like for $Var to have the value 'XYZ', but I'm willing to
defer to any settings the admin or another script may have made", while

    $Var = 'XYZ';

says "$Var should have the value 'XYZ', overriding any values another
script may set."

But that's just how I think of it.  Whatever works for each admin
is what they should go with.  :-)
