Even in the absence of strict tables, you can also add a CHECK constraint whenever limits are needed on the value types. Here is one example from a recent discussion in SQLite forum threads: `check(datetime(x, '+0 seconds') IS x)`.
SQLite has been rock-solid since attaining DO-178B, and commonly isn't ever upgraded in many installations.
CentOS 7 is using 3.7.17. Since the v3 database format is standardized, the older version can utilize a STRICT database file, but will not have the capability to alter datatype behavior.
For these cases, implementing both STRICT and the relevant CHECK constraints is advisable.
