There are not many good reasons for that. The ones I know out of my head

    - /usr can be mounted read-only, / can't

        - /usr can be mounted with noatime without loosing any features
          as it's read-mostly

    - defect isolation (something which has just bitten me very
          badly): Assuming a physical defect occurs on some part of a
          disk, this will trash a perfectly random subset of anything
          that's on this partition

    - It's possible to use dpkg -S `which <command>` to determine
          the package a particular command belongs to. With the merged
          /usr as in Debian 10, which will aways return /bin or /sbin as

    - I arrange my stuff how I want it to be arranged. I don't care
          about the file system on Lennart Poettering's laptop. I don't
          care about him re-arranging my bookshelves, either.

That said, while I think this merge is a hairbrained idea (huge
disruption for no gain), I don't really care about it, as it doesn't do
much damage.
