Really, this is the best way to start to figure out what's needed. Flex layouts take a lot of work and a lot of times add hours to a project. If the audience for your website doesn't tend to use mobile devices... then don't optimize for mobile.
I try to extend this all the way down to CSS Resets. Only use what you'll need.
Even if you get some users who are using mobile devices, mobile web browsers are remarkably modern. Chrome and Safari have mobile counterparts that will help hammer down cross device compatibility (although checking on the actual system is always recommended).
Most of the time, I design with an averaged screen size in mind. I tend to do fixed layouts more than responsive or fluid. I make sure that it's not breaking on other devices, but I tend not to go out of my way to design for them if its not needed.
