I do not dispute that deep copy is commonly used in C++. I

the idea that it is a good design pattern, i.e. better than

copy-on-write.
Ignoring the design issue, it's plain faster -- for COW you
have to
perform checks on every call.
On every write obviously. In short - it depends on the use case.
lol I thought it was rather obvious that e.g. if you never do any
calls to begin with then the point is moot... but thanks for the
clarification lol =P
