As announced earlier this year, we plan to deprecate TCP wrappers out of Fedora services in a single release (Fedora 28) to avoid user confusion that some of the tools will be using it and some not.
For more information about the change or possible migration paths outside of the package itself, see the linked accepted Fedora 28 change.
This report is for a source package, that has "BuildRequires tcp_wrappers" in spec file and resulting packages depend on "libwrap.so.0". The changes to remove the dependency should be minimal, usually a configure switch, but let me know if you will need some assistance with the changes.
I have dropped mod_wrap from proftpd builds on F-28 onwards. There is still mod_wrap2, which provides similar functionality but does not use libwrap.
Thank you for the information and a message that there is application-specific workaround for your tool. I will update the wiki to reflect this.
