You're overthinking this (or undereducated on fancy launchpad features)
and I already have a tool half written and a plan in place to smooth
this over for the next release.

There's no need for moving things to silos and such.  That's gross.  We
just mass delete everything that's not a 0-day SRU, record the versions,
and copy them into next-proposed when it opens.  LP will happily copy
deleted packages back into existence.

(The only reason this needs a tool is because we also need to track down
if the source had binaries or not, to pass the right args to copyPackage
later, but that's all done here, just needs a bit of a tidy).
