3 weeks ago Looks like this would require upgrading to at least libstdc++ 13.1, which Ubuntu 22.04 doesn't ship. Once we drop 22.04 it should be safe but until then it is likely too new still.
libstdc++ and libc++ on all of our supported distros is now new enough to support.
This should be mostly straightforward to implement, the only weird one will be fextl::fmt::vformat since it uses the fmt::basic_memory_buffer for custom allocator support. There's no direct 1:1 replacement in the C++ standard so will need some massaging.
This will remove one more external project dependency in a relatively straight forward way. Low-prio but shouldn't be terrible to do.
