The QCoreApplicationPrivate::appendApplicationPathToLibraryPaths() function has been there since at least Qt 4.5.1, so the documentation for appendLibraryPaths() hasn't matched behavior for a minimum of 13 years. The documentation for libraryPaths() has mentioned this fact, though. Searching the application's bin dir is normal on Windows, as many application packages are a flat install with the .exe and all .dlls in one dir. I find it questionable to do so on Unix, though: any and all applications expecting to be installed by a Linux distribution would not install plugins to /usr/bin, whereas on macOS bundles have their own organization anyway. But I'm not prepared to change the behavior without more justification. I can think only of broken configurations (such what is described in QTBUG-97950 where a combination of bad decisions led to scanning all of /usr/bin) and running an executable that is stored in a world-writable directory.
