Indeed, that can be seen as correcting for an unfortunate design error 
in locale file formats, influenced by the matching error in the C 
library spec.  I.e., "no grouping" should have been specified as 
determined by an empty grouping string, in which case (and only in 
that case) an empty separator string would be allowed.  But hindsight 
is 20/20, and we must patch around our forbears' mistakes, just as 
our descendants will be obliged to patch around ours.
