Of course. It's just that fairness is often given as a reason, especially since the accommodations often might be unfair in other professions, but were meant to counteract specific unfair problems. For example, spousal hiring could be seen as nepotism; in the case of Goeppert-Mayer, it famously wasn't allowed because of that. Yet outside of a handful of major cities, the local university is often the only place in the area someone can have a strong academic career, and academic careers often involve moving, so for a couple to both have academic careers, they often need to find a university willing to hire them both, and to search for positions together, something that is very difficult, especially when in different fields, unless the university has procedures to handle it. Add to this that academics often have social lives within academia, and this can become a very common difficulty.
