I worked with a client that implemented their own Python version of this to deduplicate citizen entries in a big french gov database. It worked well.

Of course, nowaday I would probably just tell them to use datasketch (https://pypi.org/project/datasketch/).

With this trip to memory lane, I looked around a little, and noticed people are still creating new stuff on the topic. E.G:

https://pypi.org/project/rensa/

Which is basically a more specialized but faster version of datasketch minhash, written in rust, with a little python on top.
