You seem to have misinterpreted the purpose of -print0 and -0. From
Linux find(1):
-print0
True; print the full file name on the standard output, followed
by a null character (instead of the newline character that -print uses).
This allows file names that contain newlines or other types of white
space to be correctly interpreted by programs that process the find
output. This option corresponds to the -0 option of xargs.
Using -0 for xargs simply means "Use \0 as otherwise \n or whitespace are
used". This also has nothing to do with POSIX compliancy, since using -0
in the first place breaks compliancy.

I suggest OpenBSD rather change their -0 semantics to match those of
every other vendor which implement -0 in xargs.
