That is fair. But keep in mind there is a difference here. DIP 
1019/1020 are _ready_, meaning they can start to be implemented 
once approved. OTOH, the better design is still just an idea, and 
no one seems to be willing to take on the task to write a DIP for 
it.

Is it a good idea to stall a useful feature indefinitely because 
there is some potential better design?

(Yes, I'm bitter and biased, but I still this is a legitimate 
question to ask.).
