Indeed, that is exactly what many FAANG companies are doing, have you noticed the slow down in velocity in major compilers regarding ISO C++ compliance?
See Apple’s slowdown on clang development and subsequent advances in Swift<->C++ interop (even going as far as merging Swift code into FoundationDB)
And ofc Google’s investment in Carbon
Or MSVC slow pace with C++23, after being the first to reach full C++20 support.
Everyone else outside the big three, is somewhere between C++14 and C++17.
