It's deeper than that. If our goal is to make the inclusion of standard
"like what happens when you install standard with d-i", then we need to
emulate what tasksel does, which is to omit all this material (and
that's considerably more than just libdb5.1, it's any package in a lib
section with Priority: standard). Now, I don't know if those libs would
be included *anyway* because they're depended on by something else that
is standard, as I haven't tried it yet, but the difference between the
two grep-dctrl's is certainly a lot more than just libdb5.1.
e.g. let's take a hypothetical libfoo that is Priority: standard but is
*not* in the middle of a transition/in a broken state in the archive,
and which no other Priority: standard package depends on. Without my
patch, it will be uselessly included in debian-live images, but d-i
images will not install it.

OK, but for this to work, you would have to run the resolver on the
whole set of packages to be included in the image to get the real
difference between the two methods. Otherwise you get something that
looks like this:
$ grep-aptavail -n -sPackage -FPriority standard -a -! -e -F Section
'^(lib|/)' | sort > magic
$ grep-aptavail -n -sPackage -FPriority standard | sort > nomagic
$ diff -u nomagic magic | diffstat
magic | 103

That's a significant reduction in packages, most of which won't be
"real" omissions because they're included by some other Priority:
standard thing.
