[U-Boot] DFU and UBIFS Volume upgrade

AFAIU, today it's possible to update a UBI partition via DFU with a new UBI
blob using 'partubi'.
However, this causes two issues/limitations:
- It erases the partition, causing PEB erase counters amnesia (contrary to
Linux ubiformat)
- It's no possible to have a volume-grained upgrade (per UBIFS volume)

I saw some (very) old threads on this subject but no conclusion. Did I miss
something? any recommendations?
