Without processing shared_preload_libraries, it's impossible to recover if custom WAL resource managers are needed. It may also pose a problem running VACUUM on a table with a custom AM, if the module implementing the AM is expecting to be loaded by shared_preload_libraries. The reason this wasn't done before was just the general principle to do fewer things in single-user mode. But it's easy enough to just set shared_preload_libraries to empty, for the same effect.
