API-wise, returning some kind of iterator/span/range is often sufficent,
and even more flexible than a full copy.

I am also not sure how relevant API here is. The only "external" consumer
of QBS API I am aware of is Qt Creator.

Implicit sharing is convenient, and it's even a solution when performance is not
crucial, e.g. classical GUI code. But I wouldn't attach that label to build
systems. Quite a few containers are never copied, yet with implicit sharing one
pays for each access "just in case" the container is copied massively, unmodified.
