After reading the whole thread again, it's becoming very clear that any disk indirection layer like LVM is a "mobile phone-like" technology: people who never really used any of its features still don't see the point, while the people who got used to it can never go back.
Very same thing with Decentralized VCS.
This is of course independent of the quality of LVM as a specific product instance.
