https://tools.ietf.org/html/rfc2474#section-6 indicates that 000001 is experimental/local use, available for standards allocation only as necessary. Pool 1 is 32 code points, of which I believe 20 are in use (figure 3 of RFC 4594). I'd rather not dip into pool 3 unnecessarily. Is there another option?
