Avri:
Would the dual stack world where routers must handle BOTH v6 and v4 tables mean that routing table bloat is more of a problem than ever? (This is a question, not rhetoric)


Yes, but there are very few levels of hierarchy, nothing like what was expected in 1993/95.  By and large the structure is flat and the tables are large and the routers can handle it, especially when you consider that routing is mostly based on AS numbers and peering rather than on prefix length.

Also living in a world where routers need to support both v6 routing information tables and v4 routing information tables, a few extra prefixes are not anybody's routing problem these days.
