Why view the offerings as too much? The goal should be fluency. Very few Americans reach the stage of fluency despite learning another language throughout middle school, high school and college. Very few. Become fluent in one language. Much better, IMO, than a smattering of a couple, which is pretty useless for anything other than being a tourist. If one wishes to become a polyglot, better and easier with fluency in a similar language.
I doubt offering Portuguese would be a case of if you build it, they will come. It’s even fairly limited as a college option, isn’t it?
