There was a problem hiding this comment.
shared_ptr is not good here, because it creates cyclic references. The UAS node holds shared_ptrs to plugin nodes. In turn, each plugin node holds a shared_ptr to the UAS node. The result is that the UAS node and the plugin nodes never get destroyed.
You can check this by loading the mavros::uas::UAS component into a component container and then unloading it. The nodes will still be there. And then load it again, every node will get duplicated.
