Blockers of apt 0.6, not related to signature verification

[Florian Weimer <fw@deneb.enyo.de>]

Hi,

are you aware of any issues that would, in your opinion, make it
infeasible to let apt 0.6 enter testing at this stage, apart from open
questions surrounding the Release signature verification (and general
reservations towards anything which might delay a release)?

Thanks,
Florian
