I think the theory is plausible, but again, just my opinion.

And I will repeat again that this is in no way, shape, or form how a design engineer would ever approach this issue. The whole idea that they would say "Oh we had RTV in a few engines so let's make a big basket so it can catch it" may be something the Bubba School of Engineering may consider but not the team of hundreds of very qualified engineers that Subaru employs. For one thing it adds costs and that will be completely against any mission statement they have!
The new pickup is in all probability there to simply improve flow all the time not to strain out wayward sealant. I have wondered if they had oil temperature issues so they added the increased air flow, oil cooler and bigger pickup to address that.
