If students' first and best-known programming language leaving college is relatively small or niche in a way that makes it unlikely to find it practical to unconditionally use it everywhere, that might actually be good for the software engineering discipline as a whole.

One healthy thing a move like that might encourage is turning which language to use into a more deliberate choice based on the virtues of the language itself with respect to a task. With Python it's kinda too easy to just always reach for the familiar whether it's actually a good fit or not.
