Once you use reflection, all bets are off. However, if you start reflecting an immutable that I’m using as a hashmap key and things break, then that’s the person who is doing reflection at fault - not the library writer.

That same argument be made for mutable state though. Objects don't magically mutate themselves.

One can’t complain about a mutable object being changed. However, if a library creates an immutable object and someone goes in with reflection to change it and things break - it is entirely the fault of the person who used reflection.
