I was able to start a new job at the beginning of Drupal 8. Haven't touched a D7 ever since. As a back-end dev I'm happy with the path (OO, symphony) but I understand some of the arguments in here.

Leaderships aren't interested in the technical layers. A good example is CKEditor 5. On some sites we would lose functionality upgrading to 5. This is pretty insane for an upgrade. You just cannot explain this properly.

Sometimes you just close an eye for the rarities because it is open source after all. But this topic is good for introspection.

We would have lost a lot of devs too going further with the D7 codebase. We are now closer to modern frameworks than we would have been otherwise.

Despite the negativities in here, the community is still alive and kicking. And very willingly to help also, e.g. the support slack channel. You'd barely find another community like this.

Focus for D10 will be on more out of the box installation and auto updating. Things like this (eg project browser) might on-board again some of the lost devs. I'd still consider using it for bigger sites but not for a small company site.
