It does, but to what extent? AIUI wodim doesn't output this text and can
be a drop-in replacement without a problem.

I agree that we need some legal expertise to confirm that. Doesn't
Debian or SPI have access to a lawyer for such cases? What is the
appropriate procedure?

I think the problem is more about GPL-compatibility than about
DFSG-freeness. DFSG #4 already allows licenses forbidding re-use of the
name or version number, and this isn't much a different case here.
