Yes, compilers will take some time to implement the new standards.

C23 seems to have decent support from a few compilers, with GCC leading the pack: https://en.cppreference.com/w/c/compiler_support/23.html

gcobol supports (or at least aims to support?) COBOL 2023: https://gcc.gnu.org/onlinedocs/gcc-15.1.0/gcobol/gcobol.html. Presumably there are other compilers working on support as well.

Intel's Fortran compiler and LFortran have partial support for Fortran 2023 (https://www.intel.com/content/www/us/en/developer/articles/t..., https://docs.lfortran.org/en/usage/). I'd guess that support both from these compilers and from other compilers (Flang?) would improve over time as well..

Flang does already support warnings for features that have breaking changes in F’2023.

Glad to hear it! Didn't turn up anything obvious in my brief search, but I was expecting some work towards newer standards at least.

Why would you expect that? There are few incentives to work on features that nobody is using.

Because given the work needed to actually get a feature into the standard I'd assume there's at least some demand motivating the addition.

I'd also be a bit hesitant about claiming that nobody is using said features. It's quite possible that the "new" feature is actually "just" a standardization of something that exists in practice. WG14 is hardly a stranger to that kind of thing, from what I understand; it wouldn't surprise me if something similar occurs for the Fortran/COBOL working groups as well.
