I don't think you need to have separate implementations to support
experimentation in most cases. Let's take the case at hand; different
object systems and links to external libraries can be supported in one
implementation. I agree with your sentiment; let the best extensions

There are some types of experimentation that might require separate
implementations, of course. Support for native threading and
compilation to machine code come to mind as examples.

I agree that one can not resolve the open issues in Scheme by fiat,
but I don't think merging implementations makes that problem worse.

And the cost of maintaining separate implementations is high.
