Is rust on an engine a case for concern? Do I need to remove it or is that purely for aesthetics?

If it runs fine don't worry too much about it although it can cause your coolant and oil line connections to develop leaks
as long as there isn't any INSIDE the engine it's fine.

That's what you get for having a downpipe
I'd be more concerned with the seals than anything.
