I like Go for this reason as well. In Python I found the Flask framework to be suitably unobtrusive enough to be nice to use (never liked Django), but deploying python is a hassle. Go is much better in that area. The error handling never bothered me either.

I think if Go shipped better support for auth/sessions in the standard library more people would use it. Having to write that code yourself (actually not very hard, but intimidating if you've never done it before) deters people and ironically the ease of creating Go packages makes it unclear which you should use if you're not going to implement it yourself.
