Because it's means there's yet another interface (along with the
command line tools, and ioctl's) to constrain any implementation
changes.  Command line tool interface will not change.  liblvm (if it
still existed as a shared library) will change drastically between 1.0
and 2.0 - not least because it in turn reflects the driver ioctl
interface.

The experimental branch has a single lvm tool, with liblvm statically
linked into it.  There's no need for the outside world to know about
liblvm.

It may be a good idea for Sistina to produce a tiny 'wrap the tools'
library for use by gui implementors.
