Please no! Much of the point of squeak is in its seamless integration
of code and non-code objects -- eg. music snippets, notes in Golgi,
images, Connectors diagrams, etc. This is *not* limited to external
projects such as Tweak or Squeakland -- or am I the only person who
hasn't abandonned the squeak of the sqCentral days, with its
'exquisite personal computing environment' ideal driving the project?

Unless that idea is completly dumped, we need much *more* attention to
updating images, not less. In that context what you are proposing is a
bit like having people lose all their emails and other personal files
everytime they upgrade their operating system.
