http://cdrkit.org/releases/ says differently:

Slow-moving maybe, but hardly "dead".

Which says:

"Although there is no "project" activity on the "fork" anymore since more than
28 months (which is more than three times of the speudo activity period), there
are still people who spread incorrect claims on both the original project and
the fork. Please help the free original project by correcting these incorrect
claims."

Unfortunately, "there are still people who spread incorrect claims" seems to
include one Joerg Schilling. Please fix your incorrect "28 months" claim, and
all similar issues.  It will help your original project's credibility.

It also says:

"In all programs of the fork that send SCSI commands, you may be unable to
access any of the CD/DVD/Blu-Ray drives at all if you are on Linux-2.6.8.1 or
later. This is due to a missing workaround for the Linux kernel interface
change that happened with Linux-2.6.8.1."

If this is the SCSI command filtering that was cleared up in 2.6.12, you
probably owe it to users to point out that little detail.  2.6.12 is over 4
years ago.  Given that when the fork happened, 2.6.17 was already current, I
could see why they didn't forward-port the fix for an issue that was only a
problem then if your kernel was already more than 2 years old, and instead just
put in doc/plattforms/README.linux:

 - Linux kernel versions between 2.6.8 and 2.6.11 are known to have invasive
   SCSI command filtering which makes the use of wodim almost inpossible or
   complicated for non-root users. Avoid those kernel versions, unless they
   have been patched to disable that filtering.

So this claim, although possibly technically correct, is vastly misleading,
especially 4 years later.

Apparently it's distributed because their legal team doesn't think it's an
illegal fork, and it's still buggy because after you relicensed to CDDL, they
felt they couldn't backport your fixes to the original GPL code.
