Photoshop: Reduce image file size by avoid storing rasterized versions of smart object raw files

An configuration option to Photoshop for avoid storing rasterized versions of layers, consisting of smart object RAW files, in order to keep the file size down.

It should be possible to regenerate the rasterization from the RAW file each time the file is opened.

It would probably take more time to open the file, but that is acceptable. And the performance may be improved by using the cache from Camera Raw?

The file format may not be backward compatible and it may require Camera Raw to be installed, but that is also acceptable.

Thanks,
