</I>
No, since there was unsupported packages in main ( think stuff like ld.so1.2 ),
and support could perfectly answer to questions depending on the contract, even
on packages in contribs.
There is also weird stuff like php-yp ( in contrib ), who was built from the same source than others
php packages, who was thus in main and supported.
No to mention that there was no process for deciding what goes in main, except that it was required
by something else in main. There is also issues of old packages that were never moved out of
main, despites not really supported.
So no, it was not clear.

There is no guarantee that the BS will always be located in France. So I think you should
not make assumptions like this.

</I>
Since the only people who will have issue with this are the president ( aka Anne )
and the people who distribute this ( ie mirrors admins ), I think we should
ask them and follow their opinions, and only theirs. Because
we can speak of "we have no problem", we will have nothing what ever we do, because we
are likely not liable. Anne and mirrors owners are. So their words is what does count.
