What if I don't have no more free DIMM slots but I already have 1 TiB NVMe and I am fine with my workload being finished slightly (or even noticeably) slower as opposed to not being able to do at all? As an example of such workload: a server, one of the many, that runs financial calculations from many web users. It's fine for it to become somewhat slower: we'll notice the performance degradation in the metrics and stop accepting new connections for a while. It is not fine for it to just die with OOM ― the users automatically will reconnect to other servers, leading to a sort of a thundering herd scenario. |

Then you obviously have a workload where having swap make sense (and you could even add swap on the fly in such a case). But that is not typical at all.
