I wonder if we could finally have that experimental package,
call it "ext" or "etc" or whatever that has only one barrier
to entry: the intent of the module must pass review. The
API and code can build up over time as people start using
it. At some point it can be called finished and thoroughly
reviewed. I think the barrier of entry is currently very high
since the reviews expect perfect quality from the start, but
good things need time to collect corner cases and use cases
that might cause major refactorings.

It's straight forward to implement for rectangles or circles,
but would any design still be good when someone tries to
implement a 2D physics engine on top of that? Would CSG
operations be part of the module? What about paths, curves and
loading from and saving to vector graphics (SVG)?
(I.e. you could literally draw the collision shape of a tree
bitmap in Inkscape and load it as 2D geometry.)
