Knowing that the target audience for this is developers (for the most part), the decision to make it a javascript application in the first place instead of rendering from the server seems like overkill, at least IMO.

Maybe it's just me, but I don't really care about fewer page reloads or having multiple animations and interactivity. I understand why those can have an impact on end users and so I do think that SPAs have their place, but I'd much rather the interface was rendered from the server and worked through links if it means it'll work faster. In fact, half the time I'm not even using the web interface; I'm using the SDKs.
