the name of the target makes people extremely likely to form incorrect
beliefs about what it targets, the name should be changed or augmented to

- If possible, use only letters, numbers, dashes and underscores for the name.

- Tier 3 targets may have unusual requirements to build or use, but must not
create legal issues or impose onerous legal terms for the Rust project or for
Rust developers or users.
