Please enlighten me. How good can a reason be to have such a conflict?

At no point in time there must ever be a reason for an Extras package
to conflict with Core. Extras packages are made for a well-known target.

Then simply back up the proposal and forward it appropriately as part of
FESCo seeking guidance by the packaging committee. Some people in FESCo
are part of the packaging committee even.

Questionable. Superfluous. Dangerous. Blocks kernel upgrades. Tries to
set up artificial hurdles for users of command-line package installers.

FC-6 does only offer a kernel >= 2.6.18, so in an Extras 6 package this
conflict adds nothing else than trouble. Looking for fun with an Anaconda
based dist upgrade?
