The __FreeBSDversion bump for permanent PFIL_HOOKS MFC existed for no more than 1 hour, so I believe that it is more or less Ok not to document the fact. It's true that there might be someone who has built their kernels in the window, but the window should be small enough not to keep so many people affected. The original rationale is to make the __FreeBSDversion consist with other -RELEASEs, and making PFIL_HOOKS does not effectively change the ABI compatibility (because PFIL_HOOKS is an optional component before the MFC, and there is no simple way to detect the existense of it). This was discussed in cvs-src, IIRC. Here is a pointer to ceri@'s suggestion: http://lists.freebsd.org/pipermail/cvs-src/2004-September/032212.html Hope that's helpful.
