IEEE 519 Current distorsion limits for h<11 order harmonics

Probably this standard is the most referred one world wide in drives power quality requirements specs. But are drives really responsible of h < 11? Aren't they very much influenced by the "upstream" grid characteristics? I mean: Of course in filter dimensioning every hi order must be considered. But ¿Aren't drive dimensioning and filter dimensioning not exactly the same thing? ¿are drives somehow over dimensioned in h < 11 current distortion limits?
I will appreciate your comments on this, thank you!
