My understanding was that the Bitcoin core devs asked package maintainers NOT to package Bitcoin core. See here:
http://bitcoinmagazine.com/5858/linux-distribution-packaging-and-bitcoin/undersigned request that distributors refrain from packaging Bitcoin node software (including bitcoind and Bitcoin-Qt) and direct users to the upstream-provided binaries instead until they understand the unique testing procedures and other requirements to achieve consensus.
Does this mean that these distributors have come to "understand the unique testing procedures and other requirements to achieve consensus?"
Edit: Link to Bitcoin-Qt package in Debian Sid:
