Hi! I did a search for serde_json on crates.io, and I noticed the results contained a number of listings that appear to be simply alternate names for the same crate. For example: serde_json_untagged, alt_serde_json, hc_serde_json, and I think there are several others. Some of them have different version numbers, but they all seem to point to the same codebase and documentation, and I haven't found any explanation of what these different names mean.

What's going on here? Do these variants actually mean anything, or are they just artifacts of the crate publishing process?
