It is situational advice, and depending on your application, not bad advice at all. It is certainly not something you want off by default, or even regularly.
In fact, the PostgreSQL 15 (and earlier) versions cover this in the documentation for the fsync and synchronous_commit parameters in section 20.5, including considerations involved in deciding when to use those arameters, along with further references in the documentation to cover more of the performance, synchronicity, and durability parameters, in detail.
