Yes, and now compare to what happened. You could differentiate between words and actions and what exactly was affected. For someone to "sabotage the Rust experiment in the kernel" you would need to determinate that that person did something that a) effectively damaged / obstructed the project (which - if GP is right about that that person has no power to stop the merging of the patch anyway - is a dubious claim), etc.
Misrepresenting the voicing of opposition to some process as "sabotage" seems completely out of line for a any kind of community project. If you define things so loosely, then every side in any disagreement could always label the other side of doing "sabotage". This reflects the sentiment of many Rust people to "be on the right side of history" where everybody else automatically is wrong and even voicing objects and criticism is already "sabotaging" on the true path.
If you don't think what Hellwig did obstructed the project, then I guess we fundamentally disagree. Again, the R4L folks could work around this by getting the code pulled in by Linus, but that doesn't stop the fact that a senior maintainer has made it explicit that they will do everything in their power to stop this.
Code that wasn't his to reject was NACKed, causing a large amount of uncertainty about how to proceed with drivers that use DMA, and around the R4L project in general. At the absolute least, this is plain intent to sabotage (but IMO it is clearly more than intent at this stage). The core of what you are saying is that this has/will have absolutely no impact on anything to do with future R4L progress. The explosion of discussions around this exact topic across various forums with abundant disagreement from maintainers and R4L folks running counter to that idea are irrelevant I guess.
I'm not even a "rust person" and nobody has said anything about "being on the right side of history" except you. If that's how you see this discussion then we're not going to get anywhere. I wish you well, and urge you to in future engage in good faith and consider that not everybody is some boogeyman "on the true path" evangelist.
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.
