My 1975 London's Railways map shows services from Broad Street to
Finsbury Park via Dalston Junction.

They went when the Northern City was connected to the GN, allowing the
services to Moorgate that FCC still run instead of the Broad St
services.

Indeed, but the tracks were not ripped up as far as I know.

Of course not but the need for the Broad St (or the replacement Liverpool
St) services was much reduced.

I have no opinion on that; just confirming that the physical
possibility is neither brand new nor ancient, which seemed to be the
question at this point.
