TL;DR
We want to improve the reliability and performance of crate downloads.
"Non-canonical downloads" (that use URLs containing hyphens or underscores where the crate published uses the opposite) are blocking these plans.
On 2023-11-20 support for "non-canonical downloads" will be disabled.
cargo users are unaffected.
Seems like they could maintain non-canonical lookups by normalizing all crate names to use underscores.
