> Not everything has a clear and fast resolution. I think Hector's team were hoping the resolution to be "Shut up everyone, we're doing Rust now, this is all merging in and that's that.!". But it could have been "Shut up everyone, we're not doing Rust any longer". They would have been even more upset saying "this is a leadership failure, they're on the wrong side of history" and so on.

I'd argue that we're basically at the point where that _is_ what the de facto policy is, except without it being actually stated. There's a subsystem maintainer blocking any Rust code from being merged (even to be imported as a dependency from outside their subsystem) who said they will do "everything in their power" to stop Rust from being merged into any part of the kernel, and when people asked Linus to clarify whether he still thought it was viable to have Rust in the kernel, he said nothing. Hector made the infamous comment about social media, and _then_ Linus stepped in to say that we needed technical debate rather than social media brigading, which gives the not-so-great precedent that invoking social media was actually more effective at getting some sort of response than the technical debate that he actually said he wants. So now, the status quo is that someone with the power to completely block any progress towards actually including any amount of Rust in the kernel will presumably continue to do so, but Linus still is sticking to the line that we can have "technical debate" about it even though the outcome is predetermined to end in failure.

You're right that not everything has a clear and fast resolution, but given that the only possible ways for this to end other than just making the "no Rust in the kernel" policy explicit is either for Linus overrule the maintainer blocking any Rust code from being merged or every single patch containing any Rust code to be blocked, it seems pretty clear to me that the way things are now is just a slower, less clear version of the negative outcome, so having a clear and fast resolution with an undesired outcome would be far better. This seems like the real cause of frustration that Hector has; it's hard not to feel like the reasons for this path to "resolution" was picked over just admitting that it's essentially official policy that Rust isn't allowed for reasons that are ultimately purely social rather than technical. The correct resolution in my opinion would be if Linus said something like "regardless of my opinion on whether Rust should be allowed in the kernel, I'm not willing to overrule the decision of the subsystem maintainer in this case, so the current status quo will remain unless someone is able to convince people to merge things on their own". My best guess for why he didn't want to do that is that it would essentially paint a target on any maintainers refusing to merge Rust code, which is understandable but seems like it will just cause more frustration in the long run than simply ending acknowledging the reality of the current situation.
