This somehow reverses the idea behind the folders in SVN. Everybody looking for 
the latest and coolest things would always look in trunk, never in a branch. 
Almost all projects have the orginal SVN structure: in A branches folder they 
do stable development and in trunk the newest things.

So I am -1 on this and I am +1 on simply creating a stable branch like it 
always was and everybody exspects. The only difference to the past is, that we 
no also do development on the stable branch.

That is also true for a branch. See e.g. PHP development. They have a trunk but 
at the moment nobody commit there (including me), we are maintaining branches 
5.2 and 5.3 at the moment.

See above.
