I would agree with that.

What happened to the proposal to add a config option to control the 
primary key selection criteria ? Did it make in into any of the 
current releases, is it still on the 'to do' list, or did it get 
dropped ?

Also, adding the ability to use this value (ie the selected key) as a 
client selector in host statements would also deal with the "assign 
address to client by option-82" that comes up fairly regularly.
