Avoiding dependencies is a good thing, especially for C++, that doesn't have a widely used centralized repository and dependency manager like npm, cargo or cpan. For the better or for the worse. And pulling Boost, let alone Qt just to avoid the occasional use of iostreams (or printf) is a bit much IMHO. I usually try to avoid Boost, as I feel it is more of a sort of beta/preview for the standard library. Don't get me wrong, it is production-worthy, but it can lead to awkward things when some boost feature ends up in the standard libraries and the project ends up with bits of both. std::format is great because at last, we can use it without dependencies.
