I have to agree - It would be much more useful if it could be applied 
per-object.

On a similar note, would it be reasonable to modify the Get/SetProperty 
API to work per object? That would be _much_ more useful than how it 
currently works, but I'm not sure how difficult the implementation 
would be. On the other hand, replacing that API with new style objects 
may be a better way to go about it. There are very few things that 
should have a strictly global effect IMHO. The global texture filtering 
settings are a constant annoyance for example, and although the depth 
buffer manipulation via the Get/SetProperty API is welcomed, it would 
be much easier to work with if the settings could be applied 
per-object.
