Can we remove the FST cache in Kuromoji and Nori analyzers?

Is the ~30k han cache in kuromoji redundant after LUCENE-8920?

The entire linked file's purpose is all around this caching, so if its not needed anymore it would be a nice cleanup. But it was definitely needed for good performance before, so we shoudl be careful. Nori analyzer has the exact same thing (file has the same name) for ~10k hangul syllables.
