Keep the installation files from Infinite flight?

Just wondering if the next flight will completely supersede the downloaded assets from last weekend’s test flight (Steam or Xbox versions). I’d like to think we don’t have to download 17GB or more again, but not holding my breath, lol. (To be clear, it’s expected at least some files would be replaced, and that there could be additional files as well, but all that usually results in a smaller “patch-sized” download). Digital licensing issues might also come into question here; not sure.
