LVM allows you to leave lots of unused space so that you can use it
where you need it when you need it without having to fuss with mount
points and figuring out how to make the mount points integrate most
effectively into your file system.
This is true, but it's a curious thing: these cures are for diseases caused by fragmenting the storage space into fixed closed partition-subworlds in the first place. You can get the same joy in your life by just having a single fully sized / partition and none of this complex stuff piled upon constricting stuff delivering nothing going on.

Unfortunately there is no way to do a clean install while preserving
some data if it is all one partition.

"No way?" I didn't try it, but booting to runlevel 1 and rm -rf /usr /boot before booting into the installation media for the "clean" install of FC(n+1) should get you to the same place. Without having to chafe on pointless restrictions and a huge workaround software stack between you and your storage during the 9 months between needing to do that.

Are there any other reasons to have partitions and LVM on boxes with one storage device and no possibility for internal expansion?
