Sure, I care most about things that simplify the way I would 
write C++17ish code: concept, requires, span, char8_t, 
[[no_unique_address]], bitcast, feature test macros…

That feature test macro approach could turn into a sleeping pill, 
though. I am in favour of it, but it puts less pressure on 
compiler vendors. It allows programmers to start using new 
features with a fall-back, but it also allows vendor to say "it 
isn't quite done, but you can use that compatibility layer 
library over there".

Clang does fairly well with C++23, so that is a bit odd, perhaps. 
I guess some C++20 features are hard to work into their internal 
representation (IIRC basically an explicit AST).
