Language design is a fine balance; the addition of Abstraction Features has to be balanced against the cognitive load it imposes on the Programmer. These abstractions also need to be tailored to a computation model supported by the language. For example, the Niklaus Wirth school of language design was famous for insisting on minimalist languages; You only added features if they were "needed" to support the model of computation and all extraneous/trivial features were omitted. C++ took the opposite route from the beginning which was ok to a certain extent since it increased the expressive power of the language (eg. multi-paradigm). But over time the balance is being lost and the cost of cognitive load is outstripping the benefit of an added abstraction. This is bad and not welcome. So looked at in this light how many of the features in Modern C++ are essential and how many are extraneous (eg. Concurrency features = Essential, variants/syntactic annotations/etc. = Extraneous)? That is the fundamental issue.
