Comment(by olly):

 Yuck!

 Brass should eliminate almost all of the overhead from long prefixes (you
 don't actually even need to store the prefix once per block necessarily -
 you can potentially reuse the prefix from the
 dividing keys in the parent block), so adding a complex and ugly mechanism
 for this in 1.2.x only to deprecate it in 1.3.0 seems unwise.  I think we
 should at least see what improvements this can deliver first.
