This is a broader question for new methods in the JDK, not just this
one. I don't think anyone has come up with a "style guide" for when to
use Stream returning as opposed to list-returning methods.
What I can say is that I think List is the better fit here, because:
- the result is not large
- the result may well be stored somewhere (method should guarantee
result is immutable)
- a List is simpler conceptually than Stream as a result type (eg.
serial vs parallel)
Personally, I only tend to return Stream if I the particular method is
returning a very large data set.
