Honestly? I'd say no. It's a sandbox. Putting a definitive 'end goal' in, even if it's optional, will subconsciously skew players into focusing on that goal, and once done with it, they're left with 'What now?' syndrome and stop playing. Happens in every single survival sandbox game

Make your own end goal if you need something like that- It is, after all, a sandbox.
