In the v2.0.6 release it was mentioned using SHA256 hash for speed and depreciating legacy MD5 hashes (and specifically that it is NOT needed to be cryptographic).
Recently the PHP community has migrated over to using, xxHash, which was officially introduced into first party PHP support since PHP 8.1 (The lowest required version in composer.json). Therefore I propose we use the xxHash implementation for its blazing fast speeds and general modernized algorithmic improvements.

Examples of the community utilising it moving forward:
