With the current draft, that is correct. With Paul's proposed changes of 27 Jun, they definitely aggregate at the LIR and RIR levels, making it much harder to defend the position that they won't end up in the DFZ.

I'm not quite following your logic here. If ARIN allocates ULA-G space from a distinct netblock, how does that make it any harder for transit providers to filter routes from fc00::/7, reduce their incentive to do so, or create an incentive not to?

If they can be aggregated, there's no reason _not_ to route them in the DFZ. With no technical incentive to filter, the financial incentive to _not_ filter will win.

ULA-L and ULA-C have a pseudorandom network part specifically to avoid any possibility of aggregation, in hopes that'll be sufficient technical incentive for them to be filtered. When you start divvying up those bits and giving them meaning, particularly a hierarchical meaning based on the RIR and LIR that assigned them, you're no longer working with "local" anything.

It's bad enough that ULA-C is reinventing PI space; we don't need ULA-G reinventing PA space.
