Well, using C++ as a C with objects has always been a choice. One I personally believe in. That means you basically write a C program, then when it makes sense you create c++ classes/templates as needed. At first this sounds like the C++ features are infrequently used, but the last major project I wrote like this, probably 90% of the code was encapsulated. But there was very little class->class communication outside of a few global classes due to the use of a dbus like abstraction allowing all the individual classes to communicate out of band. (sort of like a collection of micro services if you will all running in the same process as different threads using a global message broker).
