Fast and compact vector format

Would it be possible to add a bit representation for vectors which uses hamming distance for similarity scoring?
It is 32x smaller than full float-based vectors, very fast to compare (XOR + popcnt) and doesn’t sacrifice too much in quality. Other engines like elasticsearch and Vespa support it for this reason.

Given the Redis focus on speed and in-memory data I’d have thought this would be an ideal feature.
Users could pass bytes as hex or base64 strings. Queries could have a min similarity (aka max distance) to control match quality.
