Question
In C++, features like exceptions impact your whole program: you can either disable them in your whole program, or you need to deal with them throughout your code. As a famous article on C++ Report puts it:
Counter-intuitively, the hard part of coding exceptions is not the explicit throws and catches. The really hard part of using exceptions is to write all the intervening code in such a way that an arbitrary exception can propagate from its throw site to its handler, arriving safely and without damaging other parts of the program along the way.
Since even new throws exceptions, every function needs to provide basic exception safety
Explanation / Answer
I would nominate concurrency as a 'whole team' feature.
Although it is possible to design the software such that only a few experts need to be aware of concurrency issues and the rest of the team can reap the benefits without being concerned with the complexities (like you can do with templates), in practice it does not work that way. In practice, if you have multiple threads, then you have to analyse carefully for each and every variable you use if there are potential concurrency issues with that use.
