The big problem I have is that there is no evidence that #pragma once
would actually help in practice. It helps in some super-special case,
involving 200 basically empty files that all include each other and
nothing else. I suspect (without any evidence) that if someone came
along and said "I added #pragma once to the boost headers, and it sped
up compilation by X% on windows, and didn't slow things down on
linux / mac os x, and it didn't break any test or library", they might
well get a less luke-warm response.
