I just tried using dd with conv=fsync option and that kinda does what
you mentioned. I see this at the end of strace:
---------------------------------
write(1, "<some data...>"..., 512) = 512
read(0, ""..., 512)                = 0
fsync(1)                           = 0
close(0)                           = 0
close(1)                           = 0
---------------------------------

So, maybe GNU folks just don't want to have yet another tool for this.
