I strongly disagree. It's quite obvious that the C++ standard library does not need to add support for "common things", because they already exist as third-party modules.

In fact, this obsession to add all sorts of cruft to the C++ standard is the reason we're having this discussion.

If there is no widely adopted JSON or DB library for C++ then who in their right mind would believe it would be a good idea to force one into the standard?

And don't get me started on the sheer lunacy of the proposal to add a GUI library. Talk about a brain-dead idea.

People working on other programming language stacks already learned this lesson a lot of time ago. There's the core language and there's the never-ending pile of third-party modules. Some are well-made and well thought-out, others aren't. That doesn't matter, because these can be replaced whenever anyone feels like it. This is not the case if a poorly thought-out component is added to an ISO standard.
