I don't think the "one-step solution" you mention was common. Will's themes tend to do things a bit differently. I'm not sure which one you were using as ThemeFlood is the name of the entire collection of themes.
... that said a collection of stacks like Foundry (or Foundation or a few others) is intended to give folks more flexibility. One person's beauty is another person's ugly. With Foundry you can create 40 px between stack blocks (if you want), or create different spacing schemas depending on whether the device used by the end user is desktop, table, phone. But there's a small price to be paid for this extra flexibility: things like what you want aren't built in for you, but it is very easy as @webinjection mentions to create your own design spacing approach.
A traditional theme tries to make it as simple as possible for the designer to get a look just as presented in the theme. That's great! But a non-theme theme like Foundry is trying to give the designer lots of extra flexibility in terms of how they design their websites. That's great too!
