Neither of these are true. In addition, you truly have no idea of

Does this mean that you can not recompile the sources and get a
kernel that will function with all the usual Mac OS X
applications? I am getting tired of poor filesystem performance
and I was just thinking that I might spend a weekend fixing the
obvious stuff in the VFS layer.
As folks have noted, it is a special concern of the kernel team that
it be possible for the kernel sources to be buildable by a third
party into a viable replacement for the shipped kernel binary.
If you're looking at making changes to the VFS layer, and you want
them to be generally useful (by this I mean picked up and used for
future Darwin versions) then I'd encourage you to go ahead and design
your changes, then check in with someone like Terry Lambert to get a
feel for how reasonable they might be in the context of Apple's
ongoing work in that area.
If you just want to tweak the bits for yourself, then the only caveat
I would offer is that as with drivers, many of the filesystems are
implemented as plug-in modules for the kernel and you may find
yourself with binary compatibility problems.
