Agreed that Danforth would be a definite stretch for that moniker. IMO Upper Beaches/Beach Hill should be Kingston Road, but there's a bit of blending with Gerrard among the residential areas in between. Genuinely curious, would you consider Gerrard more in line with Danforth Village?
As a West Ender, I've always lived in a borderline area that can be associated with Davenport, Corso Italia, or Junction Triangle.
The rail corridor is a fairly material dividing line in terms of area feel.
So Gerrard definitely feels different than Danforth.
There are no streetcar routes north of Gerrard, except for the tail end of same as it reaches Main Stn.
The homes are typically of a different vintage etc.
But Gerrard, particularly once you've topped out, from Woodbine to points east, feels markedly different from the Beach.
Though, as Kingston Road climbs the hill as well, you get a bit more connection east of Main.
I think aside from straight proximity and vibe, the question of connection to an area is one of ease of access on foot.
Gerrard at Woodbine, involves a large hill to the south, and a large hill to the north. So the area stands apart to me.
Gerrard at Coxwell and at Main has a much easier connection to Kingston Rd. (roughly level).
But a connection to the Beach, even at those easier points seems tenuous to me, at best.
