Sounds like a good strategy.

What do you mean by “change”? Never noticed anything.

I just found out that with Tika and Gotenberg you can also supply office type documents to Paperless. So I figured there are people using this for files that might change in the future because you e.g. added another paragraph to a text document. You essentially have the same file twice but in different versions. But I guess that is not really the use-case. It is more for “official” documents that don’t change anymore.
