C++ Coroutines Do Not Spark Joy

Big +1 to this. Most of the changes to C++ have been fixing old problems. Concepts are a complex feature sure, but before having named concepts in code, we had unnamed concepts in code that may or may not be named in the documentation. Being able to name these things in code and get reasonable error messages from the compiler / just actually be able to understand it in my brain is great!

Same with constexpr. People used to do all sorts of stupid math / string concatenation in "template metaprogramming" to get compile time execution. Now they write (mostly) normal functions in standard C++ that I can actually read. The language gets more complex sure, but the code I read and write gets simpler.

C++20 is larger than C++11, sure. But for most users, it's simpler too.

It will not fix all the pre-existing legacy code that people deal with on a daily basis. Languages are like infrastructure. People need to get it right on day one since it's exceedingly expensive to fix later on after people have already started to build on top of it.
