I think it's OK. From devices.txt:

---
The prefix /dev/sr (instead of /dev/scd) has been deprecated.
( ... )
(in recommended links)
/dev/scd?       sr?             hard            Alternate SCSI CD-ROM name
---

The recommendation is to have a hardlink here. But i think symlink is OK.

To me, this is still very bizarre.

+ X0R -> null
+ ramdisk -> ram0
o ram -> ram1
x lirc -> lirc0
x vbi -> vbi0
+ radio -> radio0
x video -> video0
x fb -> fb0
+ ftape -> qft0
x sbpcd -> sbpcd0
o xpram* -> slram*

The ones with + are from devices.txt.

The links mark with x I thought they can still
be there. Is common to point the /dev/foo symlink
to the current /dev/fooN that's in use (usually
the first one, foo0). If user don't wants these links
he can always overwrite those links with custom rules
in /etc/udev/rules.d.

I don't know about the ones I mark with o.

I like tty with MODE="0620". But 600 isn't bad.

The udev rules shipped with fuse-2.7.4 have
MODE="0666" in there. Maybe isn't better to leave
this to fuse package?
