Other languages are complicated too.

Just compare Java 10, C# 7.3, Python 3.6, .... to their initial designs.

However I do agree with you and Bjarne, having also submitted this link awhile ago.

C++20 should have been fixing what was left from C++17, specially regarding concepts and modules.

Instead there are a plethora of other issues, and some of them it isn't even clear what is coming with C++23.
