AngularJS is deprecated?

How long is SailPoint going to support/use AngularJS? Based on the AngularJS website (AngularJS), the technology is deprecated, and the LTS for it ends on 12/31/2021. I am interested in this because I want to know the implications of writing a new Single Page application in an IIQ Full Page plugin in AngularJS, which I understand is the currently recommended approach to writing IIQ Full Page plugins.

On the page you linked, there is this message at the top of the page:

This site and all of its contents are referring to AngularJS (version 1.x), if you are looking for the latest Angular, please visit angular.io.

I suppose the question is now: Which version of AngularJS will SailPoint include.

This is the guide to upgrade from AngularJS to Angular:
https://angular.io/guide/upgrade

Angular and AngularJS are different technologies; and AngularJS is deprecated. The Angular upgrade path from AngularJS is more a migration to Angular from AngularJS (as opposed to upgrading AngularJS to a different version). Do you know if IIQ will upgrade/migrate to Angular in the near future? Or, perhaps IIQ will change the framework they use, like choosing to use reactJs, viewJS, VAADIN, or something else?
