Well yes. The point is only that it is possible in Java, the denial of which
is what I was objecting to.

Furthermore, interface designs are indeed done in practice when necessary
precisely since they address the situations when dependencies need to be
controlled.

Actually no. This is highly unusual. The vast majority of implementation
classes would reside in different files from their inferfaces.
