I get the impression that most desktop users enable zram or zswap to get a little bit more out of their RAM but there is never any real worry about OOM, not regularly anyway, so then (according to the principles laid out in the article) it shouldn't matter much.

On my workstation, I run statistical simulations in R which can be wasteful with memory and cause a lot of transient memory pressure, and for that scenario I do like that zswap works alongside regular swap. Especially when combined with the advice from https://makedebianfunagainandlearnhowtodoothercoolstufftoo.c... to wake up kswapd early, it really does seem to make a difference.
