What's the difference between conda-mapping.prefix.dev and compressed_mapping.json?

[yueyinqiu]

When installing a PyPI package, I noticed it accessed both https://conda-mapping.prefix.dev/hash-v0/xxxxxxx and https://raw.githubusercontent.com/prefix-dev/parselmouth/main/files/compressed_mapping.json. I'm wondering why both are used at the same time; do they serve different purposes?

In fact, accessing the former one is not that convenient in my network environment. So, would it be acceptable to have it return a 404 and only rely on the latter?

Thanks in advance.

One is based on the hash of packages and the other on just the package name. We use both if just the hashes are not enough. We are moving both to the same prefix.dev account.
