I think the focus points recorded in the image are often irrelevant, e.g.
if you use focus-then-recompose. The focus data in the image would probably
show the central focus point, which may easily point at the background by
the time the picture is taken. (I realise this is less of an issue with
touchscreen focus on MILC and images taken with a phone).

I was thinking more of an analogy to the
indication of sharpness in lighttable (ctrl-z).
This would mean a similar drawing, but a way
simpler task of finding the spots, which must
be really hard when qualifying image detail.
