// `ProfileTokenQuality` is associated with one `AutofillProfile` and tracks if
// the supported types of that profile are accepted or edited after filling.
// It is intended to collect observations on form submission using
// `AddObservationsForFilledForm()`.
//
// The observations (accessible via `GetObservationsForFieldType()`) can be used
// to understand of the quality of a supported type. This has applications for
// e.g. voting ("high quality votes") and detection of quasi-duplicate profiles.
// No applications are implemented yet.
//
// Observations are only stored for stored types. The observations of derived
// types use the observations of the corresponding stored type. When collecting
// an observation for a derived type, it is stored as an observation for the
// corresponding stored type.
// See `components/autofill/README.md` for details on stored and derived types.
