visually no, but then i don't create things without an id.
in terms of complexity, yes.  i find out i need one, i ask, i get.  i  
dont need to search for the last one that was created at any point.

so i'm thinking... you got caught out forgetting to set an id.... i'm  
betting you learned from it and it hasn't happened again. right?

so perhaps we're trying to solve a problem we don't have?

in normal circumstances the only place UUID-like entries occur is in  
the status section where the node's UUID is included in a  
concatenation with other values to form an id (in which case the UUID  
is used multiple times and should be compressible).

not really since the resource id is always unique.
