Loadable builtins are quite mature at bash version 5.2.37(1)-release (x86_64-redhat-linux-gnu). But Fedora ships without the /usr/lib/bash/ directory where bash's make install puts the binaries.
Although the sources reside in the examples/loadables/ directory, the distributed ones are supported.
Debian & Ubuntu provide the loadable builtins in a package called "bash-builtins".
Slackware comes with loadable builtins installed as part of bash.
I suggest Fedora takes one of the above approaches.
Historical Note: Loadable builtins first appeared in bash 2.0. Binaries (what Fedora still lacks) appeared in bash 4.4. 

Reproducible: Always

`help finfo` should now give you:
