Depends on your definition of mainstream computing. Samsung's f2fs has been in the linux kernel for many years and is used on their Android devices. It can be used on desktop or server SSDs and gives impressive results on some workloads compared to more traditional ones like ext4, but I've been steering clear of it because at least in 2019 it had really bad error detection (just silently discarding most i/o errors, not something you'd want in a filesystem):

It may have improved since then, who knows.
