[Qgis-developer] Query building for rasters, too

One of the great new features is the ability to create entirely new
vector layers from existing ones based on certain criteria. I was
surprised that there didn't exist similar functionality for rasters.
E. g., it should be possible to create a new raster layer containing
specific themal values from an existing one that had categorized pixel
values, perhaps using the result of a call to
GDALRasterBand::GetCategoryNames() or GDALRasterAttributeTable
contents. I did not see any plan for implementing such after
stumbling through the various qgis related web sites, including the
wiki and the trac site. Is there a plan to implement such a feature?
