Is there any hope of that happening? Instead of abstracting and over specifying sqlite, can the spec just specify a version of the SQLite API browsers should support and roll the version periodically?
Even if the spec just listed occasional version and the webpage could choose which one; that means a potentially tricky maintenance burden on browser to support old versions of a potentially no longer supported sqlite, and each version is another megabyte.
Why not then just choose this solution, and let each website pick its own poison?
If the concern is the repeated downloads of common resources, well, we've accepted that for other CDN's too, and a solution for shared caching of common dependencies would in any case be more valuable than merely for sqlite.
The current approach seems better than a browser-provided version.
Now we get the most recent version of SQLite when we need it as a 410KB compressd WASM blob, as opposed to being stuck on browser-mandated versions of SQLite that might even be a decade old at this point.
