Stefan-Bolzmann law in n-dimensions, what is wrong

[exponent137]

In one old version in wikipedia, the Stefan-Boltzmann law was derived in n-dimensions:
https://en.wikipedia.org/w/index.ph...Stefan–Boltzmann's_law_in_n-dimensional_space

Then one theoretical physicist come and deleted it:
https://en.wikipedia.org/w/index.php?title=Stefan–Boltzmann_law&oldid=758438490

His reason was:
Deleted section on law in n-dimensional space; little physical relevance; hardly belongs in a textbook, certainly not an encyclopedia. Associated paper by Giddings has a total of 5 citations on Google scholar to date..

What is really the problem with this derivation that it cannot belong to wikipedia or to a textbook? We cannot test it, but the derivation is straightforward, are there any alternative?

Hm, on the first glance it looks right to me. Only indeed the reason given is valid. As long as there's no clear evidence for extra dimensions (and afaik there are indeed none today at all) it's pretty irrelevant for a general-purpose encyclopedia (or even a physics textbook).
