GTFS validation: referential integrity errors in transfers.txt

[ansoncfit]

Referential integrity errors have high severity, so bundles containing them cannot be used to create projects or run analyses. Recent MBTA feeds have contained referential integrity errors in transfers.txt:

#1 | transfers.txt:5744to_trip_id | Boat-F1-1000-Long-BF2H-02-Saturday-Summer-23
#2 | transfers.txt:5687to_trip_id | Boat-F1-1810-Hingham-BF1-06-Weekday-Summer-23

We don't currently use transfers.txt in a meaningful way. Should we downgrade the severity of referential integrity errors in files we don't use to medium?
