You bring up a good point -- maybe something I should emphasize more in this blog post.

Demos should be inclusive of all he work it takes to build a real, functioning piece of software. That should include the reliability work, the scaling, the testing, and the refactoring necessary to do real software engineering. And it should include APIs and containerization. So I guess I'm intending this as a fairly technical demo, but talked about from a customer and business perspective.

I personally think it's important for your stakeholders to understand the necessity of this work, and this gives the team the chance to talk about it.

Thanks for bringing up the failure mode of this -- I'll consider adding that to the blog post.
