Yes, HCE regularily downloads the svn, adds his stuff on top.
and tests with one or more rc versions before release.

Therefore it makes sense to propagate any fixes to mainstream
because then the diff will be smaller and his job easier
and it contributes to mainstream with both generic
and AVR32 stuff.

One of the key issues for an AVR32 developer is that they cannot
commit additions to the Atmel version, so every time
a new version is released, they have to port their stuff to the
Atmel version.

Why do you think that noone is using them, there are thousands
of AVR32 boards sold every year, and if the Atmel buildroot
is the recommended way of providing the Linux, that is the route
many will follow.

It really does not matter. The Atmel branch fills one need,
and the AVR32 support in the main trunk fills another need.
The Atmel branch would have been much less useful
for AVR32 developers if people like John Voltz, Thiego & others
had not worked with the main trunk

My idea is based on that if buildroot works, then noone
should need to have a personal stable branch because
buildroot will contain the personal stable branch
without much addition.

Unfortunately people equates having several package versions inside 
buildroot
with having to test different permutations of those packages.

That just mean that either they have not read what I have written
or they have not understood so I repeat:

My proposal means that the test effort will only use ONE VERSION of each 
package.
The release will only support one version of each package.
It is in the development phase, where you get more versions,
and when you move to a new package version in a new distribution
you FREEZE the old versions, but you do not remove them
and you do not allow the casual user to select them through Kconfig.

You can however select to build an older distribution and then the older
versions will be used.
There is no immediate way to mix packages from  different distribution
suing Kconfig
A developer is free to select whatever package he wants by creating
his own distribution using overrides.
