Hi Adam
That was my take on why the 'heat' is no longer there.
The fires of 2019-20 burnt that area fairly badly. The scrub in places
is now very tough going, but would have been easier in say mid-to-late 2020.
cheers
Tom

says that "The Global Heatmap shows 'heat' made by aggregated, public
activities *over the last year.*"
So it's possible there were routes showing when the original mapper
mapped this but they've expired now.

My view is also that Strava heatmaps are insufficient on their own
to prove a track. They do show that a reasonable number of people
have passed along a particular route in recent times. They don't
prove a path or track, and they give no indication of permissions.
However I did look for details of way 963735356 in the Strava
heatmap, and there's very little in Strava in that area. It's
possible the user did have the heatmap open in iD but didn't trace
all the routes from there. Some might be 'local knowledge'.
I do make use of the strava heatmaps frequently to refine the route
of known tracks, especially if there's lots of tree cover and you
can't see the tracks too well in imagery.
10s or 100s of averaged GPS tracks is better than a single GPS track
which you might record yourself.

Do people have a view on the armchair mapping of tracks from Strava
heatmaps?
I can see a bunch of tracks in Kanangra-Boyd NP that have been
mapped by
an overseas mapper off Strava heatmap.
They almost certainly don't exist on the ground. They are known
bushwalking routes (off track), but would be very unlikely to
have a
track even in good times, let along after the fires and 3 years
of La Nina!
Example:
