Comment(by ahocevar):

 The WMC and OWSContext tests failing is a concern. It should be possible
 to configure layers without the opacity set. This is why I think that a
 default of null makes sense, meaning "we don't bother". It isn't that hard
 to deal with this on the application level. See e.g.
 http://trac.geoext.org/browser/core/trunk/geoext/lib/GeoExt/widgets/LayerOpacitySlider.js?rev=2605#L213
 for how this is done in GeoExt - it goes along with checking if we have a
 layer and doesn't hurt at all.
