Backlog
Leveraging more from Web Components when it reaches universal adoption in major browsers (e.g. CLI command that compiles *.vue files into vanilla web components).
Built-in class-based API when class properties and decorators reach stage 4
Leveraging Web Assembly when it gains better DOM access capabilities
