diagnostics

The diagnostics feature is unsupported and might be removed.
It enables some low-overhead timing features used in our development cycle.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
