Yes, %e will be removed in one of the next versions for that reason. It
never worked reliably outside of udevstart, which is no longer
recommended to use.
Yuu can match on ENV{ID_PATH} with custom rules for every device. On
SUSE, the system management creates rules on installation or update, to
have always the same names for optical drives, regardless of the order
of discovery:
$ cat /etc/udev/rules.d/65-cdrom.rules
# cdrom links generated by YaST2
#
SUBSYSTEM=="block", ENV{ID_PATH}=="pci-0000:00:1f.2-scsi-1:0:0:0", SYMLINK+="cdrecorder cdrom"
Distros could also have a "default" rule, which catches unconfigured
devices and automatically creates a rule for them to keep the name
stable across reboots.
