Correct. It was a requirement for all aircraft to report @ 30nm inbound.
When the remote Flight Service units closed and responsibility for their airspace transferred to the centres the AFIZ service continued, with the consoles providing that service having the remote aerodrome's met info (wind speed, direction, temp, QNH) displayed. I think the centres also provided an ATIS on the remote aerodrome's NDB & VOR where equipped.
When FS disappeared and responsibility for their airspace was taken over by ATC, the remote AFIZ function ceased.
It does sound like this SAFIS proposal recreates this i.e. an AFIS provided at remote aerodromes from BN & ML centres, this time with the benefit of ADS-B or SSR surveillance.
