Companies like Stellantis are very keen on brands using standardized platforms. I would be very surprised if in the future Volvos weren't using engineered in China Platforms, which are localized for Europe (same for Land Rover with engineered in India).
If Swedish engineers are just developing hats, their influence on crash safety is significantly reduced. Right now Volvo still uses an inhouse platform, where they do actually have control, but it is obviously inefficient to develop numerous similar platforms for different brands.
Sure, but we should be clear that it's speculation on future behavior (sound as it may be). That has not happened (yet). Some MNC's succeed in not killing the goose that lays the golden eggs (I'm also speculating)
