And who gets to implement those ideas faster, many of which were never implemented before being added into the standard in first place?
The surviving three compilers are already lagging as it is, none of them is fully 100% C++20 compliant, C++23 might only become 100% on two of them, lets see how C++26 compliance turns out to be, meanwhile C++17 parallel algorithms are only fully available in one of them, while the two other ones require TBB and libstdc++ to actually make use of them.
I'm obviously not talking about modules-level features that may never get to see the light of day.
A random(min, max) function isn't rocket science and already a major inprovement over the three-liner that is currently necessary. The major compiler devs won't take long to implement these cases, just as it did not take them long to implement simple yet useful functionality in previous versions of the standard. And the standard library is full with these cases of missing convenience functions over deliberately over-engineered functions.
Modules have already seen the light of day in VC++ and clang.
Anyone using a recent version of Office, is using code that was written with C++20 modules.
It is relatively easy to see how far behind compiler developers are regarding even basic features.
Note that two of the three major surviving compilers are open source projects, and in all three major compilers, the big names have ramped down their contributions, as they rather invest into their own languages, seeing the current versions as good enough for existing codebases.
