Hard pass. There are globs of features and design changes that make it worth the switch immediately if your use context can allow for it. I've now done a handful of apps and libraries in it, and given the option, I'd never look back to node. I don't say that lately. Node's was the best. These new designs are more than marginally overcoming the shortcomings of node. The motivation for migration is strong, and if best proven through experimenting. If you are TS saavy, do yourself a favor and try it out.
