Well that's a shitty naming scheme. We'd end up with half of everything named "iso" and the other half named "rfc". Or worse, some meaningless number combination like "802.11".
It's not less arbitrary to remember than any consumer-friendly name like "Wi-Fi" or something (in fact, if you know the IEEE naming standard then it is a little bit easier to remember)
Furthermore naming technology after their standard has the advantage that anyone that says it support that technology must support the standard, altough such a construction is also possible with arbitrary named (e.g. "Wi-Fi certified" which is a trademark which you can only use after standards compliance tests)
