'meta_type' is ignored if the object exists already. I guess you don't 
propose to support meta_type changes.

Updating properties selectively should work already. AFAICS the only 
missing part for your example is the non-purging (=update) mode 
implementation for type-info actions.


I hope we can get rid of the non-purging mode in the long run, but the 
delta profile based solution is still vaporware, so improving the 
non-purging mode makes sense if you need something workable right now.


No objections here.
