OK, that makes sense.

Going forward I will watch for such Q&D edits in the generated
files and try to address those in xdrgen. I would like to avoid
actually /committing/ such edits, though, because IMO we are
pretty active here right now and can get the "long term" fix
done quickly.

Meanwhile, I've updated the xdrgen patches in nfsd-next to
address many (or maybe all) of your requests from yesterday.

The header file is now split between

  include/linux/sunrpc/xdrgen/nfs4.h (protocol definitions)

and

  fs/nfsd/nfs4xdr_gen.h (function declarations)
