This is true, because supporting an init system requires every package
that provides a daemon to work with that init system's boot scripts.
And you can't really define a single format for boot scripts, because
that's a fundamental part of how an init system works.

Editors, on the other hand, are interchangeable in terms of usage:
all of them work with
$EDITOR $file

I'm not sure how "include the init scripts for all init systems in the
core package" is not technically feasible.

Delta support was proposed but voted down on the grounds that it only
works nicely for upgrades where you know the baseline.
If that's correct, it would be most problematic for cross-release
upgrades.

I'm not sure what you mean by "alternative package chains".

No automated ways, true.
It's possible to do it manually via snapshots.debian.org.
It should be *possible* to use the package meta-information and dpkg
logs to roll it back automatically, and if you don't clean your package
cache that's also an option.

If it's a new package, it works fine:
# add deb-src ... stretch ... to a squeeze box
# apt-get update

# Try with a new package:
apt-get source motif
# it works!

# try with an old package
apt-get source -t=stretch bash
Reading package lists...
Building dependency tree...
Reading state information...
E: Ignore unavailable target release 'stretch' of package 'bash'
E: Unable to find a source package for

This seems like -t is parsed without checking whether it's source or
binary, which is a rather annoying bug.

But it's rather annoying that there's no way to automatically get it
from the VCS.

I'm inclined to think these are readily solved by extending the package
format and package managers.
