Autoconf includes logic to probe for various compiler features and

These probes have a bunch of problems and they currently don't
include anything newer than about 2017 for either C or C++.
Actually, I contributed support for C23 to bleeding-edge Autoconf. But
as I avoid C++ there's nothing in Autoconf yet for C++20 or C++23.
the biggest problem with them is NOT that they
are out of date, but that they do not allow the package being
configured to declare which edition of the language standard they
want.
For C this has not been a major problem as far as I know. There should
be simple workarounds for bleeding-edge Autoconf as-is, though of course
it would be nice to make Autoconf better.
C++ is a different beast, though. It'd be helpful to get real C++
expertise involved here.
