I haven't tried c++17 year, but c++98->c++11 did bring about code bloat. However even though we were building the same code base for two different systems, one without a C++11 compiler (thus we could not use c++11 features): it is incorrect to say we were not using C++11.

Just turning on C++11 in the compiler brings move to all standard library containers. The header files were not just "somehow" linked in and not used, the additional code was used in many places behind the scene. I haven't done benchmarks on my code, but the general report of those who have is that in exchange for the extra binary size the code runtime was 5% faster. For most people these days that expense is worth it.

What do you mean by code bloat?

Binary size after compiled. Also time to build - just turning on C++11 more than doubles the time to run the processor. (I hope C++20 modules fixes this)
