Following up myself: The reason I prefer stable device names instead
of UUIDs or LABELs is that device names show up in some places even if
you use UUID or LABEL in /etc/fstab or in your command line:

On my laptop I have UUID in /etc/fstab but df still shows the device
name:

$ grep -w / /etc/fstab
# / was on /dev/nvme0n1p2 during installation
UUID=c73ff331-0ff5-44fb-8aef-228e64a96175 /               ext4    errors=remount-ro 0       1
$ df | grep -w /
/dev/nvme0n1p2  237470384 107725172 117659352  48% /

On my server with LVM I get:

$ grep -w / /etc/fstab
/dev/mapper/vg0-root   /               ext4    errors=remount-ro 0       1
$ df | grep -w /
/dev/mapper/vg0-root              2031440     659132   1261556  35% /
