Partitionning behaviour of the installer

The installer proposes to use LVM. If one chooses this option and the default partitioning, the root partition is relatively small and the home partition uses xfs and all the remaining disk space. If the root partition gets full, it is not possible to shrink the home part because it is xfs, so the only solution is to reinstall.

While if ext4 would be used, it would be a simple lvresize command to shrink /home and the same to increase size of root partition.

I have no clue what the advantage of xfs over ext4 is, but in this case, using xfs for a file system that takes all space in the volume group makes it impossible to resize anything, which I thought was the main benefit of LVM. So I find this kind of default choice rather poor.
