We know it's out of date because "This is signalled by setting the MSB of the first octet, and provides for 95-bit integer size, i.e. 32768 YiB (it's so big that we lack a better prefix for it)." ;) In 2022 ronna- became the recognized prefix for 10^27 and earlier this year robi- became the recognized prefix for 2^90. 32768 YiB is 32RiB. Jupiter has a mass of 1.9 Rkg. After that is quetta- for 10^30 and quebi- for 2^100. The Sun has a mass of 2 Qkg.
