The reason I suggested stderr was because it is about the only channel you can have a reasonable guarantee of being able to use from a library that has no knowledge about its execution environment. Security policies applied to procesess (SELinux, seccomp, namespaces or containerization in general) can easily prevent ability to use journald, syslog, or opening of log files, leading to messages not being visible. At worst, with seccomp an attempt to use the blocked feature may lead to an abort of the application.
