I use the `lv`, `pv`, and `e2fsprogs` families of commands pretty routinely in my day job (we minimally logical volume filesystems on hosts and leave it up to application/deployment/user what to do with the bulk of the storage) and haven't found this to be a real issue. After a couple minutes thinking about what you're doing, you never really need to revisit this. You should probably spend a few minutes thinking about what you're going to be doing when dealing with your filesystems anyway.
