Unfortunately, strict mode is incompatible with name-based type mapping: if you have a column that you want to be an RFC 3339 date-time (e.g. "2023-06-06T23:25:27+11:00"), for example, the only spelling permitted for the column type is “TEXT”, whereas without strict mode you can name it “DATETIME” or similar and popular libraries in various languages will automatically map that to the language’s datetime type (according to local conventions, not anything universally defined—e.g. https://docs.rs/sqlx/latest/sqlx/sqlite/types/index.html https://docs.rs/sqlx/latest/sqlx/sqlite/types/index.html shows the built-in mappings the Rust sqlx library has decided to support). This destroys the ergonomics of strict mode for me, rendering strict mode quite undesirable, since it’s basically fighting with a more useful sort of strictness.
