About tracking issues

Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.

cc @bjorn3 -- wanted to file something official for this internal unstable detail (don't think anything existed already).

#102318 is not really useful as the alloc error handler is still part of the allocator shim. #112331 would entirely remove the allocation error handler. After that the allocator shim only contains the __rust_alloc_error_handler_should_panic static when #[global_allocator] is used. Maybe a weak static in liballoc with the default value when -Zoom is not passed would work for that?
