This all comes down to "no silver bullets" and "there are no solutions, only trade-offs".

You can have codebase x for free, but depending on future changes is risky, especially if it's close to your core. A larger team are likely to be more stable, but be less amenable to any specific changes you want. You can fork the code, or provide patches, but this adds extra complexity you'll need to manage.
