So, consicely I agree that small changes in lay out would not matter, but I'm not sure about a rigorous change in the default css and overridable xsl-templates, but I would welcome every change in css and xsl, to make it easier for you (and everybody else) to get it right without copy-pasting.
Aside from this (which I agree with), I think it is definitely useful (if not needful) to have some examples showing that - and how - you can change the look and feel to get to something more fitting for your website.
It would be a step forward if we can add your layout to the examples (as we did with the 3-voor-12 layout).
