We sped up Notion in the browser with WASM SQLite

Pretty cool. First time I'd heard about the web locks api. https://developer.mozilla.org/en-US/docs/Web/API/Web_Locks_A...

This part:

Is incorrect. The primary development browser for the two VFS APIs they're writing about is Firefox. (Citation: that development all happens on my computer.)

Blog post author here -- I wasn't totally clear, but what I meant was that we didn't have the capacity to do the work to make Notion fully cross origin isolated (which would have indeed worked on all the major browsers). That meant we could only roll it out on the browsers that provided this temporary workaround for it.

Great write up; but honestly all I could think is what a blunder it was when Mozilla vetoed shipping SQLite.
