I guess it falls somewhere in the middle - the flag refers to the 
'environment' so I believe it hasn't really been considered as applying 
to the registry - IOW, the reference to 'environment' probably refers to 
the specific 'environment variables' rather than the more general 
'execution environment'.

I agree.

Others will have opinions which carry more weight than mine, but I see 
no reason it should not be fixed for *some* Python version.  Assuming no 
objections from anyone else, I suggest the best way to get this to 
happen in the short to medium term would be to open a bug with a patch. 
  A bug without a patch would also be worthwhile but would almost 
certainly cause it to be pushed back to a future 3.x version...
