The e-mail app clobbers the console.log() implementation so that it uses dump() under the hood and adds pretty colors.  We also put that shim inside our worker.  So inside e-mail, console.* is preferred.

But in other apps/worker contexts where you're just trying to see something and they haven't replaced console.* or you don't have it (worker, at least previously), dump on its own isn't bad.  But yeah, you definitely need to add the newline yourself in that case.
