A few updates:

While decorators have reached stage 3, we saw some behavior in the spec that needed to be discussed with the champions. Between addressing that and reviewing the changes, we expect decorators will be implemented in the next version.
Rather than shipping pieces of module resolution, we’d like to have a cohesive story on each of the above. That will likely be going to the next version as well.
Caching in .tsbuildinfo files is still in flux. We’ll likely have to decide on that only if we feel like we can get sufficient coverage.
