As far as reasoning goes, ten points. It doesn’t help with the fact that it’s still pretty generic and frequent word/name both alone and as a part of a compositum (see: https://corpora.uni-leipzig.de/en/res?corpusId=eng_news_2024&word=void ) though.

I don’t mean to be negative, but the name is generic and second brain as a term is not really descriptive at all. In fact I hope that second brain as a term never really catches on. Why that name though?

If tag/classification based and automated sorting is not the thing the end-user can live with, then Paperless-ngx isn’t the solution, but if you have Nextcloud and you add both the to-be-preserved directory structure and Paperless-ngx’s consume directory as external storage, you can have both with a little manual labour.
