Strange because if every browser adopts sqlite why not let people use it ? W3c will not prevent people using some tech ? Ofc it won't be standard, until it is? Soon, sqlite implementations may even fork and then we would need standardising.

I think that the ultimate result (sqlite-wasm) is better than what Web SQL database could provide. Today you can bundle your own version with your own set of native extensions. In case of standard Web SQL you would be forced to check the version and figure out, is it finally possible to use RETURNING in queries.
