Reduce usage of nighlty features

psp/src/panic.rs breaks a lot lately, maybe gate this under a cargo feature and use panic = "abort" by default.

This issue should probably be renamed, the issue with panics seems to be some sort of linker change upstream in rust-lld. My general suggestion would be to move to unwinding and figure out what workaround mitigates the underlying issue/isolate what change in rust-lld broke them in the first place.

In lieu of that, panic support should be dropped outright, though I think that would be rather unfortunate.

No, don't think it's just about the panics. In general we would want this to reduce severity of future breakages. If we want to focus on a specific aspect, we could open a new issue or PR for that.

Fair enough, though I suppose an effort should be made to enumerate the most fragile things. Ie/ internal features dependencies, and so on.

But yeah I'll probably spin off a separate issue about panics, tried to get discussion going about it on discord, but it seems it's dead in the water for now. 🙂
