Great news, domain constraint enforcement is a welcome new feature. However, let's not throw the baby out with the bathwater; being able to specify an ANYTYPE/VARIANT column on a STRICT table would make this feature more useful. The canonical use case for ANYTYPE is a BIGTABLE or Entity–Attribute–Value (EAV) model.

I haven't checked recently, but I was unable to determine the type of ? parameters in SQLite prepared statements. Maybe this is something that can also be accommodated with STRICT tables.
