Good plan.

The AppleScript support was there maybe even before Illustrator was available for Windows.

Not going to look at either API. And, I don't have a current Illustrator.

...but I can guess with certainty that the javascript API gets more attention within Adobe. And that it has a more solid future.

AppleScript may never disappear from Illustrator or macOS. But it _does not_ have a bright, vibrant future.
