I totally agree. And in fact, this state of affairs is what prompted
me to start this discussion with the question about 'next steps'. I am
really hoping that, if some simple policies can be established quickly
after the svn switch, it will be far more easy to move forward than
by having two switches: one to svn (replacing 'HEAD' by 'trunk', but
no new policies), and one to a new development process (stable vs. branches).

I'd suggest this:

* establish a 'stable' branch (by copying from RC_1_34_0). This is easy, and
  should be done *now*. (Then regression testing should be set up to monitor
  this branch's health.)

* establish goals for 1.35, notably by defining a list of accepted but otherwise
  new libraries to be added, and encourage library authors to work towards that
  goal (branching from 'stable', adding code, testing, submitting self-contained
  patches to be merged into stable, etc.). This should be easy, too: one trac
  ticket per new library.

* Discouraging developers to check *anything* into trunk any more, but instead,
  encourage the use of branches as a means to backport changes that now are in
  trunk, and should go into stable, whether in time for 1.35 or not.

There clearly are a lot of refinements and improvements that need to be done in
the above, but they all can be done incrementally. The important thing is to
get the ball rolling (into the right direction).
