This reminds me that years ago someone implemented support to save
plists in a binary format[1] (this doesn't necessarily mean that it
would help solve this problem, though).  But I'm surprised that since
all these years the support wasn't added; anyone know if there is
general resistance to an optional compact and portable binary format,
and if so, the reasons?

If such a format was supported, it wouldn't be harder to machine or
human-process (proplib could be used as it is now for code, and bplists
could be easily exported to an xml format as requested to edit in an
editor, i.e. via a viplist, plistctl or such command (which also could
use advisory locking, of course, and save back to binary format if the
system is configured to use a binary format).  In theory, it could also
increase performance, and a binary format would be simpler to parse by
the kernel than xml, minimizing bugs...
