So yes, agreed with Tobie et al. Another thing to keep in mind here is that it's pretty easy to convert between either of these behaviors. It's just a matter of either doing requestPermission().then((r) => { if (!r) throw Error(...) }) requestPermission().then(() => true, () => false) Or, using the await syntax async function() { if (!await requestPermission()) throw Error(...); } async function() { hasPermission = true; try { await requestPermission(); } catch { hasPermission = false; } } So I think a more important question here is what behavior would an author expect. I think one of the points Dominic tried to make earlier is that the name is important for setting that expectation and help authors understand how the function behaves. Sadly the name that we're stuck with doesn't really provide much guidance either way. But I think to some extent it's indicating that we're bikeshedding here. / Jonas
