Checks if a plugin is installed. Whilst the other methods check this too, it only returns values if they're enabled or not, whereas this is just a check if something is installed regardless of enabled status. Useful to check for IPC things if a plugin has been disabled without the user really noticing, or if it just isn't installed at all.
