@RobLoach can you elaborate o what we get by doing this that we otherwise don't?

@RobLoach – did you answer @thiagodemellobueno offline?
What is twing? What problem are we solving?

[RobLoach]

While Twig.js is great, there are some inconsistencies in the output. We have differences between how Drupal outputs a component vs how Kalastatic outputs a component. Using Twing would output the exact same result in either KSTAT or Drupal.

I closed this for now because Twing.js is still pretty young. Perhaps I'll consider it again down the line, but for now, Twig.js is good.
