Be very concerned in about 18 months. That is the time it will take to implement/publish and then you will see the gradual enforcement take place over an additional two or three years. Everything that flies remotely beyond 400 feet distance will require both active WiFi connectivity (controller smart device) and broadcast RFID from the drone. If your drone does not meet that requirement, your flights will be limited to areas that the local community has pre-authorized for hobbyists and received FAA approval to fly (like a sanctioned flying field) or vacant swampland. So you are NOT grandfathered but you will be allowed to fly about 1.3 football fields (400 feet) in community designated areas. Good luck getting your community to agree to let you have your own designated drone fly area in a place that you would like to film, lol.
Next scenario, you're in a remote area, canyon, desert, lake, etc. if you don't have WiFi connectivity but your drone can broadcast RFID....too bad, it wont take off without WiFi connectivity too.
To be crystal clear, this does not appear to be something to worry about ....YET! By the time you need to worry, you will have ditched your drone and purchased one with an RFID Standard System or given up the hobby (3+ years) from now.
If you enjoy this as a hobby, you did not have an advocate for the current proposal. The commercial market wins hands down $$$. So, if you want the FAA to listen, you better give them constructive/problem resolution solutions starting January through February. They are taking your suggestions. Complaining does nothing, offer solutions that can work or kiss your hobby goodbye.
