The thing about /dev/sd[a-z][0-9] and older ata /dev/hd[a-z][0-9] as well as NVMe and USB device names is that they are controller, port and/or plug-in order dependent.
If you have bunch of drives connected to any of these interfaces at boot time. They are enumerated by controller/port/partition order. If you mix them up you get different device names - thus - if you can still boot from the mixed up drives - you end up with wrong drives mounted to wrong mount points. Some times adding internal hard drive, depending on controller/port order can mess things up spectacularly. Well, this can get much more "interesting" with the external USB devices. Example: You have external backup drive connect to USB host root 0, port 0 and it always shows up as /dev/sdc. Then you get new computer plug it to usb3 port which can be USB host root 2, port 2 and some times you will get /dev/sdc, some times even /dev/sdf depending what you have plugged in, where and when. Add to this - making USB copy by dd or disk cloning - which will create above mentioned mount point conflict and broken/stale file handle in /media/$USER/ and you have perfect recipe for perpetual, randomly repeating "entertainment" for years to come. And did I mentioned systemd yet? Or external enclosures with port multiplyers and SAS/SATA switches or scsi emulation? This is obviously very difficult to diagnose and trouble shoot over the email. So, I believe that for many reasons, using UUIDs to mount stuff is pragmatic choice for better life satisfaction.
