Where do you draw the line with compatibility? There's lots of small, DB specific differences like this between all the databases (mysql, sql server, postgres etc).

For this particular one, you can replace interval with something like `last_at < DATETIME(CURRENT_TIMESTAMP, '-10 day')`

I think this is a fair point, if you think you'll run into sqlite's limitations in the future. litestream and friends make sqlite an option for some non-embedded use cases.. though they're hardly a panacea.
