Yes it is being maintained. I would recommend to take a look at the demo site that is in the plugin page that contains many usage demos.
As for the states they are not initialized by default. You will need to attach event listeners to activate the states. Just keep in mind that any action you perform on the map should happen after the map ready state is yes
The demo page has proper usage examples that includes marker removal
Thanks for the answer @AliFarahat
