You're missing the point -- it's a bad precedent.

How many kernel forks and patches exist out there on the net?

Many of these patches will get merged eventually. But it is a bad idea
to include bits of such into the Linus tree, when they are not used in
the Linus tree.

-Exceptions- to this policy should be carefully considered... reserving
syscall and sysctl numbers certainly makes sense. Bloating kernel_stat
with tons of unused numbers, some specific to web servers AFAICS, does
not make sense.

Tangent: Why is this webserver-specific crap in kernel_stat anyway? It
looks like there should be a separate per-cpu structure for webserver
statistics.

Even when merging Tux, I would hope Linus would not apply this
particular change.
