The really nice thing about using subvolumes is that you don't have to
guess and hope that you get the sizes right for the / and /home
partitions.  I remember many times when I would create too many VMs or
something in the / partition and run out of space when there was still
lots of room in /home.  Or doing system upgrades was a big one.  I would
often symlink the cache into /home.  Or you run out of space in /home,
but there's still lots left in /.  Now, there's only one partition and /
and /home are just subvolumes.  So the total space is shared and you
only run out when it's all gone.

If the notion of **partitions have a size** has gone right out the
window, why bother to try to do anything that's remotely like it?  Just
have one "/" partition and have everything in it just as a directory.

Because the subvolumes are still separate. You can do backups of specific subvolumes. You can re-install the / subvolume without wiping the /home data. You can do quotas. If you have a secondary drive, you can use subvolumes to add space in specific locations in the tree.
