Using these templates does help understand good layout because the examples have already shown 85% or more of how a common consumer or saas app needs to display web UI. By implementing them, mixing and matching, you get a feel for how it aught to be because there are plenty of examples. Simply by using these you can become more mindful of design. Asking a dev to start from zero and learn design is not realistic and for a potential solo technical startup founder a waste of time. If designers don't understand bootstrap layouts that's fine. But if a developer doesn't they are not trying. And these templates don't fall apart from small changes, they are built responsive from the get go and have tons of helper classes so developers can still alter them without hacking them up.
