The current implementation of DevFS resembles the linux devtmpfs, and not the traditional DevFS, so let's rename it to better represent the direction of the development in regard to this filesystem. The abbreviation for DevTmpFS is still "dev", because it doesn't add value as a commandline option to make it longer. In quick summary - DevFS in unix OSes is simply a static filesystem, so device nodes are generated and removed by the kernel code. DevTmpFS is a "modern reinvention" of the DevFS, so it is much more like a TmpFS in the sense that not only it's stored entirely in RAM, but the userland is responsible to add and remove devices nodes as it sees fit, and no kernel code is directly being involved to keep the filesystem in sync.
