You're going in quite the wrong direction here.  The consensus as I
understood it was that we should just use the text representation in
binary mode too, rather than inventing a separate representation that's
going to put a whole new set of constraints on what can happen to the
internal representation.  The proposal you have here has no redeeming
social value whatever, because nobody cares about the I/O efficiency
for aclitem (and even if anyone did, you've made no case that this would
actually be more efficient to use on the client side).
