app property
Null when the storefront knows no such app.
Absence is an answer, not a failure, and the command still exits
non-zero to say which answer it was — notOnStorefrontExit, 6. A caller
reading this document therefore has both halves: the status to branch on,
and display to print.
A nullable object rather than a found flag beside flat fields, so a
release date cannot be read without the null having been dealt with.
Two facts arrive here as one, and that is the endpoint's doing: an
app that has never been released and an app that is not sold on
country's storefront both answer with no results. It is why --country
is a flag rather than a constant.
