It's only one datapoint, but at this very moment a server at work is using a notable amount of swap, 1.5 GiB to be more precise, while functioning perfectly normally.

    $ free -h
                  total        used        free      shared  buff/cache   available
    Mem:          3.9Gi       1.7Gi       573Mi       180Mi       1.6Gi       1.7Gi
    Swap:         4.0Gi       1.5Gi       2.5Gi

I wish you luck! Only time that’s happened before was memory leaks for me, and it didn’t go very long before death spiraling. But if you’re comfortable with it, enjoy.

It's still working just fine, with still the same amount of swap in use (approximately).
