It's mostly easy to wire up a new plugin where none was before. Most of the plugin functionality will be enabled. You'd only need a restart to work around any plugins with an optional dependency on the newly installed plugin IF they do hard caching.... This is exceedingly rare, so for the 99.9% case you can install a new plugin for the first time without restarting.
For uninstall, however, jenkins cannot know which plugins are maintaining a reference to the uninstalled plugin resources, so a restart is always required.
