True; we could just say "earlier", but I am inclined to suggest that
we get drop it altogether.  Description of historical bugs is of no
interest with the version that already fixes them, so the _only_
value the doc update adds is to tell readers that the untracked
cache feature is still not well proven, and core.untrackedCache may
serve as an escape hatch from its bugs by disabling the mechanism
added for the feature.  I am *not* opposed to a replacement of the
patch that just says something like "This feature has been cause of
bugs even in recent versions of Git, and you may want to disable it
as a workaround when you are hit by an otherwise undiscovered bug in
this area", though.
