It's not quite that simple. The WebSQL standard wasn't a "standard" at all, it was just "browsers already expose whatever SQLite they have, lets write that down!". No tests, no conformity, no way to tell if browser X supported SQLite feature Y, nothing. Just raw access to whatever SQLite was baked in. There were lots of inconsistencies. Yeah, it was super simple and useful, but nobody wanted to do the work to make sure interoperability was a thing, in part because SQLite has very complex behavior and lots of quirks to adhere to.
