Your change should become available through our snapshot versions in ~15 minutes or so; we release every two weeks, with the next one scheduled for Wednesday. Hope that helps!

And if you spot any more improvements we'd love to hear. There's no need to create an issue first, although it's appreciated when you call out existing issues as you did here. 😊
