It's good idea, but in my opinion while freezing option is not bad at all, this should not be used for such a thing. Freezing and locking should be independent. When this kind of feature is added, it should work transparently and should not save png files to svg, maybe only to /tmp when needed. On loading everything has to get generated again and all generated objects should get stored. Also it would have to be controlled by options in preferences: enabling (enabling means large footprint in memory) 10% zoom - how many percent of zooming makes it to regenerate image
But as I will not write the code, just ignore it :)

Using lots of blurred graphics in the same document can bring a computer to it's knees. Similarly, CPU intensive synths in a music sequencing application can do the same thing. In many music sequencers, there is a feature that allows you to freeze a music track by turning the synth's audio into a small WAV file and turning the synth off. Perhaps a similar feature could be introduced in Inkscape. By freezing an object (i.e. a group of blurred objects), it becomes a temporary PNG that is displayed in place of the real object. The real object exists in the document, but it is hidden from view. The temp freeze image can be moved around the canvas, but not edited at all. If you want to edit the object, simply unfreeze the object to delete the temp image and unhide the original object.
Currently, you can hide and lock objects. What is missing is a means of exporting an object as PNG, locking and hiding the original object, importing the temporary PNG at the same size and location as the original object, then syncing the location of the original object with the temporary image.
At bare minimum, a feature that would export a selected object as PNG and import the new PNG to a newly created layer (named "png copy of xyz_object") - all in one step would be a nice step in the right direction. Then, all I would need to do is hide the original object. If I want to edit the object, I can delete the PNG layer and unhide the original object.
