which requires creating a file and going through file interface
why would memory access need such intermediary levels which can
be done directly from NVMeOF target ?

Also, in-future if we want to extend or implement any NVMe specific
feature then any such intermediary layers will make things hard.
With nvmet-mem-backend you can easily implement that in the target.
