I was thinking about this, and it occurred to me that we could have
"false positives".  E.g., project.el might set the variable and add it
to file-local-settings, but then some later hook might setq the
variable as well.  In this situation C-h v would incorrectly say that
the variable had a project setting -- unless every setq manipulated
file-local-settings.  The reason this is bad is that the point of
mentioning this in C-h v is to avoid confusion resulting variables
magically being set -- but in this situation you would be just as
confused trying (mistakenly) to debug your .emacs-settings.el.
