I've also encountered the issues using gdal_calc with non-homogenous
layers (which is why I started looking at the raster calculator).
Another reason I would like to see the native calc working is because
it runs much faster than having to wrap third-party tools. I've found
gdal is generally not too bad, but my use-case is still to build a
model and loop through it hundreds of times, so every second counts.

My feeling is that it wouldn't take much work to get the raster
calculator at least usable in the modeler at its current level of
functionality. Improving gdal_calc or implementing more powerful
operators in native raster calculator can then be a secondary, more
involved process.
