Imagine i upload a new nobootloader version, with some changes in it. I either
upload it directly, without revision system, or with my own shadow copy of the
d-i svn like above.

Now, someone else needs to modify nobootloader. He is not aware of my changes,
commits to the d-i svn, and uploads the package. My changes are lost.

Next time i upload my changes, i may well not notice that there was another
upload, and the other changes are lost. (Well, probably not, because i will
have some svk based tool to merge those changes into my tree).

So, we end up in a mess, because there is no more only a single authoritative
(or even juste a single) copy of the repository for the package.

This is the reason why i am arguing against the current proposal which doesn't
restore my svn d-i access, and why i have not even tried to do any d-i work
since then.
