please corret me if I'm wrong,

as far as I understand you can allways override
package versions in a buildout.cfg file which will extend the
kgs.cfg which uses allowed-picked-versions=false flag.

What you can't do is, using a KGS file with allowed-picked-versions=false
and use a package which defines another versions for other controlled
packages then defined in the KGS without to re-define the newer versions
for the "other" packages too in your custom buildout.cfg.

The goal of using a KGS is to fix versions at a central place
and prevent using versions which get defined in packages
(different then in KGS).

I guess what you like to get is the option to define a new
version for a specific package and this package pulls in other
package versions. And then the allowed-pciked-versions flag
forces buildout to raise an error till you define all new versions
in your buildout.cfg (explicit override)

If you remove the allowed-picked-versions flag, you will make
the KGS concept unstable but at the same time there will no
error get raised.

The only goal of removing the allowed-picked-version flag 
is if someone does not like to re-define the different package
versions which get pulled in if you change s single new
package version because this new package uses other new packages.
But then we don't talk about a "known good set" that's more a
"known starter set".

My summary,
as far as I understand removing allow-picked-versions
delegates the version control to the packages. right?

anyway,
it doesn't really matter to me since we define allow-picked-version=false
in our projects. I just like to know everybody that this is not
a simple change.
