A senior maintainer has a different opinion and expresses it. Your point seems to be that because he is not on board with the plan and expresses this, this is already "sabotage". Of course it makes things harder if not everybody agrees. But this is not the same thing that people disagreeing with your plan and say so do "sabotage". Sorry, this is ridiculous.

There is a large difference between "I do not think this is a good idea" vs "do not do this", in particular given the position Hellwig has in the kernel as a listed maintainer of the DMA mapping helpers.

No single technical reason was given besides a non-specific opinion on the "messiness" of multi-language projects.
