AFAICS on a 1TB disk the space allocated to the root partition/volume is 
about 60GB (~5%), not 30.

IME even 30GB is more than enough in many desktop use cases. My own root 
filesystem (including /var) uses less than 10GB. However on smaller disk 
sizes such as 250GB, it has been reported that the root filesystem may 
be too small in some use cases, so one may consider raising the root 
filesystem priority in partman-auto "home" and "multi" recipes a bit.

This distinction already exists: guided partitioning offers a "server" 
recipe, which allocates most disk space to /srv instead of /home. But 
the space allocated to / is about the same as in "home" and "multi".

Guided partitioning with LVM gives the option to reserve some free space 
in the VG for future allocation. You can use this space to grow logical 
volumes as needed.
