"... the new keyword is now optional...". Why optional and not deprecated?

  Deprecating it is a breaking change and would make migrating code more difficult. It's like how semicolons are allowed but rarely used in Ruby, Go, etc. The style guide says to omit "new" [1], and our formatter can remove them for you [2], so the effect is that they are gone without the pain of a forced migration.
