Remove packages in t-p-u which migrated already?

[Luca Falavigna <dktrkranz@debian.org>]

Hi,

I ran a patched version of dak cruft-report [0] to consider as cruft
packages with an higher or equal version of those available in an
enhanced suite (unstable vs. experimental and testing vs.
testing-proposed-updates). Currently, cruft-reports checks for higher
versions only.

As of today, cruft-report marked bind9 as the only candidate for
removal (1:9.8.4.dfsg.P1-1 >> 1:9.8.1.dfsg.P1-4.4), while my patched
version revealed a much longer list [1].

I wonder whether it could be possible to safely decruft those packages
(by eventually deploying my patch in dak), or whether it is better to
leave them in place.
