Comment(by pracine):

 So I see just two options to solve this:

 1) We add a nodata value parameter and this nodata value is used just if
 the requested band do not have a nodata value defined (if it does the
 passed nodata value is ignored). If this option is chosen I would also
 expect to be able to give an extent to the raster/raster variants.

 2) We remove the possibility to get an other extent then the
 'INTERSECTION'.

 That said I like the fact that we have (in some cases) the possibility to
 get an extent other  than 'INTERSECTION' taking for granted that only the
 intersection is always filled with data...
