This need not be the case.  Ian's current plan with Jitter is actually to SIMPLIFY the bytecode engine, thus hopefully easing the porting process.  JITTER is built as a plug-in, so it neither complicates the VM significantly, nor adds space for minimal implementations.  Once the basic engine is running, one can go on to the JITTER as a separate project.
