I didn't say that there *is* no use-case, only that I have never found one.

Perhaps you have misunderstood the English idiom "Without a convincing 
use-case...". This isn't meant to imply that there is no use-case, only 
that nobody has yet found one. The implication is that, if you wish to 
promote this change to Python's behaviour, showing a convincing use-case 
is a necessary first step. (But not the only step.)
