On the one hand yes, what you say makes a lot of sense. In an ideal world you'd have dev, staging, production, all using different configs. Of course then they might different pushes to production might fail.

But one of the things that I'm testing is that SSL, HST-pinning, etc, is working. So I could fuck around with adding "--header" arguments to curl, etc. But really I want to test in a browser and if the name doesn't match I'll have issues.
