Will the April release land in Fedora 42? If you use -std=gnu17 for now, then it might obscure problems in extensions. If you can't backport the C23 compatibility fixes and can't do the extra compatibility work for extensions, maybe it's necessary to stick with -std=gnu17 for Fedora 42 and switch it off for Fedora 43 only. (Worst case, C23 source code compatibility could be an ABI-incompatible change, but it's unlikely because the extension API must already be source-compatible with C++.)
