In my case, I'm extremely close/occasionally under the flight path for BWI, and just barely inside the 5 mile perimeter. Thus, I filed for the registration with FAA. The (very helpful!) FAA fellow tried to talk me out of it and almost had me convinced until we couldn't find a contact number to notify the tower when I fly.
He happily registered me so I can fly whenever I want within part 107 regs (e.g. - daytime, not over people, etc), within 0.1 NM of my house, without calling BWI. He even extended the registration to a full year. The
Tello range doesn't exceed my permit, so I'm good to go.
It was a painless process to know I'm avoiding the dark suit men in the black Lincoln from coming to my house...
