@ggivo I don't think it's a breaking change, since the files are internal and not used extrernaly.

@uglide
What do you mean by not used externaly?
They are marked @deprecated but are public and not documented as internal in comments or annotated with @internal.

@ggivo see https://github.com/redis/jedis/pull/4311/files#diff-a1c95bbe6e3dc70afb41f29448973d7f61021891667a064b67d5bbc2603748b3L32-L35
This PR removes leftovers that were overseen during the JedisSharding removal. Hashing was used only for JedisSharding and is unlikely to be used without it.
