Can you find any evidence that it's acceptable to interleave multiple writers that are doing O_APPEND? At best, to do what you're asking, they could be kept from being interleaved from the context of one specific NFS client host...
As far as POSIX goes, the standard says that applications are expected to handle serialization. It makes no exception for O_APPEND.
Then let's fix IO_UNIT so the existing code can DTRT.
