I recently upgraded a D8 site to D9 using Composer. However, I have since come across an issue when I use the site's existing Bartik theme. I have since found out that in D9, Bartik no longer extends Classy as its' base theme. 

Q: For existing D8 sites that have a customised v8 Bartik theme that use Classy, how can a v8 Bartik theme be successfully transitioned to v9 (as part of the D8 -> D9 upgrade process) when Classy no longer extends? Doing a clean install of Drupal 9, there is no problems using the core Bartik theme that comes as part of the install.
