(Which is fair enough given the extensive use they make of OSM maps for display and routing)

I use Strava heatmaps only as a "referential" source, i.e. seeing
potentially missing or badly misaligned paths and then taking a
walk that way. In addition to other comments about using them
directly, I'd also wonder whether Strava copyright allows it but
have not explicitly analysed.
In Sweden, I have found them a great referential source, but then
we have "all man's right" and off-path walking is not generally an
issue so there are many useful informal paths.

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!
