i'll bet there is an implementation of hfs+ in the mach layer.

mach needs to understand the filesystem well enough to load the server
from it. i ported hfsutils (yes, the userland stuff) to the mach layer's
bootstrap code back when the only way to install mklinux was with a macos
util and a tarball.  i'll bet mach has an hfs+ implementation (albeit
read-only) in its bootstrap section in darwin.

i realize you're right that the read/write implementation would be in the
bsd layer as i think about it...

the best route may be to enhance hfsutils for hfs+ support. you don't have
to worry about the complexity of multiple readers/writers that way but you
get a useful, practical result. then jump into writing the kernel code
after it works satisfactorily.
