I would imagine that the simple answer is "consistency."

The slightly longer answer, IMO:

Would you like to make snapshots for consistent backups?  That's enabled 
by LVM.  Would you like to accelerate magnetic disks using SSD-backed 
cache?  That's enabled by LVM.  Would you like storage for virtual 
machines with low overhead?  That's enabled by LVM.

Personally, I think all of those are relevant to desktop systems.  I 
make use of those features on my home desktop.  And while not everyone 
does, there's really no reason to exclude the component that would allow 
them to do so when they decide that they would like to.

Those are benefits to users.  Developers (Anaconda and dracut, maybe 
others) benefit from having a consistent configuration that's supported 
from laptops up to servers.  The more consistent those systems are, the 
better tested the storage stack is, and the more stable it will be for 
everyone.

Unless you have a snapshot of a volume, LVM doesn't have a measurable 
overhead.
