There's a limited amount of exterior wall space. If you give the bedrooms windows then that pushes the living space to the interior and makes it window less.

That's how my freshman dorm was. Moving exterior to interior it was bedrooms, study space, and then a shared living room. The result was windows in the bedroom, where they were mostly covered with blinds, and no windows in the living area.

That's the wrong compromise. You want the light in the living areas where people are spending their days. Of all the different trade offs windowless bedrooms is 100% the right call.
