VIN locked CE parts?

So, I was thinking about the possibility of CE parts being VIN locked. I know there has been a lot of interest for future core owners to obtain CE specific parts. Now, I believe Toyota has the same part numbers (for the most part) for universal parts (with the only ones different are in respect to LHD or RHD specific parts). With that being said, "in theory" the bulged and vented hood "should" be available to order without being VIN locked. Obviously I'm just speculating here, and I could totally be wrong because JDM vehicles don't have VIN's like NA cars do. But, the standard JDM trim for the GRC is the RZ, which comes with the bulged and vented hood. I don't believe the RZ will come with the CE spoiler though, at least it wasn't pictured with a big wang like the pre-production CE was rocking. So the spoiler may in fact be VIN locked, especially if it is only offered on the NA CE. I'm guessing the CE seats will also probably be VIN locked, as they are standard on the JDM RZ, but they are also RHD/LHD specific to an extent (at least the rails and what side the seat belt attaches to). The CF roof skin as well "in theory" should not be VIN locked (I mean I doubt any core owner would want to spend the money that Toyota would sell that thing for...).

Again, I'm just speculating here. What do y'all think?
