Ah, but what about all those other operations that use strings under the covers? As mentioned, namespace lookups do, among other things. And how is performance in the (very real) case where a C routine wants to return a value to Python as a string, where the data is currently guaranteed to be ASCII (previously using PyUnicode_FromString, now able to use PyUnicode_FromKindAndData)? Again, I'm sure this has been gone into in great detail before the PEP was accepted (am I negative-bikeshedding here? "atomic reactoring"???), and I'm sure that the gains outweigh the costs.
