The real problem with LVM - as it is with Windows "dynamic disks" is the problem of recovery when a drive goes down. While backup is the only sure recovery method, it is desirable to have tools that can recover such systems if necessary - simply because some people won't backup and will end up needing recovery. For a consultant with such clients, tools are necessary.
It is possible apparently to recover from a corrupted LVM or downed drive, but it also apparently is much more difficult than recovering a normal file system failure.
These points should always be discussed when considering a non-standard file system layout.
