Reallocate not possible in RAID0, so unusable in V-series?

I'm reading the TR-3929 Reallocate best practices document. I've ran "reallocate measure -o" on all volumes across all our V-series filers. Most of the volumes come back with an allocation check of over 3, meaning a reallocation is recommended. Not really surprising since I've grown the aggregates over time with array LUNs from the backend storage.

 

The TR recommends physical reallocate, but also states that this is not possible for RAID0 aggregates. But since I get RAID protection from my backend storage, I of course run all my aggregates as RAID0. Does this mean I can't really do reallocate? Or that the traditional reallocation would be my only choice?
