I think the problem is that C++ is a poorly designed language with a fundamentally flawed development process.
Instead of letting compiler implementers decide which features to add and how to implement them, C++ employs a standards-first, top-down approach. Features are often defined by committee members who may not use modern C++ in their daily workflows, leaving it entirely up to the individual implementations to catch up.
Some features were standardized back in 2023, yet not a single implementation supports them in 2026.
