Though I agree with the importance, I feel I must present another side.
I've not researched what the IETF wishes to re-purpose 418 for; however, I might be more amiable towards the re-purpose if it were going towards, say, a 'honey pot' status.
Some might argue 418 Honey Pot might draw more flies to the internet. I feel though, if properly implimented, it could be a great upgrade to what, I believe, is less used.
Tea pots today just aren't as popular in the millennial age. Fortunately, perhaps a 418 Honey Pot would help bring awareness of our diminishing honey bee population to more.
