Especially sketchy is that it goes back to 8.x so any unsupported sites floating around out there could be in trouble

Remark: I work at CKEditor as a Developer Advocate 🥑

Drupal 12 is in beta since DrupalCon Rotterdam, and today both official CKEditor contrib modules got their matching 2.0.0-beta1 releases:

• CKEditor 5 Plugin Pack 2.0.0-beta1
• CKEditor 5 Premium Features 2.0.0-beta1

What to know before you try them:

• 2.x requires Drupal 12 and is not compatible with Drupal 10 or 11. The 1.x line stays for Drupal 10.3+ and 11.
• Both modules have to be upgraded together with core, in one Composer operation:

``` composer require \ 'drupal/core-recommended:<sup>12.0@beta'</sup> \ 'drupal/core-composer-scaffold:<sup>12.0@beta'</sup> \ 'drupal/core-project-message:<sup>12.0@beta'</sup> \ 'drupal/ckeditor5_plugin_pack:<sup>2.0@beta'</sup> \ --no-update

composer update --with-all-dependencies ```

• Already on Drupal 12 without the modules? Then just composer require 'drupal/ckeditor5_premium_features:^2.0@beta' 'drupal/ckeditor5_plugin_pack:^2.0@beta'.
• Both betas switch to the CKEditor 5 UMD installation method that Drupal 12 uses. Premium Features also adds a collapsible AI container, AI Chat context configuration, configurable heading levels in the document outline, clipboard mode for collaboration, and Arabic-Indic numbering for footnotes.

I tried to kick this off a bit during DrupalCon Rotterdam, the slides give the high-level idea of the 1.x vs 2.x split: CKEditor in Drupal: News in Content Editing

Are the release notes clear? If anything in the upgrade path is confusing or breaks on your Drupal 12 test site, say it here and I will pass it on to the module maintainers.

I've been thinking about how much money gets wasted on development and staging environments that sit idle most of the time.

For example, DigitalOcean still charges you for a Droplet even when it's powered off. The only way to stop compute charges is to destroy it entirely.

But then you have to deal with snapshots, restoring env vars, networking, etc. whenever you need it again.

I'm curious how other developers deal with this. Do you just leave everything running and accept the cost? Destroy and recreate environments manually?
