Ohhh found the non power Jira user! Gitea is good enough for your org. Without knowing your requirements this is pretty much a blanket statement. Gitea is nowhere near good enough for a large engineering org.
Example: groovy integration with Jira allows an enterprise to build their own custom workflows. Like integrating with your Vcs to enforce funded work (requiring an open Jira issue in git commits). Features like this, until recently, left them in a league of their own. GitHub Actions has leveled that playing field. Gitlab and gitea can fight it out with bugzilla, but you won’t find them in most engineering orgs.
Another example: building out complex dev roadmaps ahead of time with constraints and relationships. Bridging the gap between dev, product, and project management
