Support for any studio larger than a few people is the most important part of 3rd party tools. If (and inevitably, when) a tool has a bug or can't do something you need, there's reassurance being able to tell someone else to fix the problem.

Using abandoned tools either means you're very sure all use cases are covered, or that your own engineers are willing to hack around should it not be sufficient. And I think anyone who works with legacy code knows that navigating already written codebases without guidance can take just as long as whipping up a custom implementation.
