Counterpoint: each new edition will add bloat to SQLite as future edition will need to keep each past edition pragma set for backward compatibility.

As SQLite is often used embedded, bloat matters.

So I suggest that "PRAGMA edition" to be only be a shortcut to a list of PRAGMA commands, that would be expanded at the library level: PRAGMA edition would never appear in the DB file. As such, the build of the library would just support a limited set of editions, with a removal policy in default builds. Maybe editions could even be defined at runtime (a system table?) as a way to load them dynamically if old editions are needed beyond builtin support (think about the state of SQLite in 2046).
