With Chrome deprecating Manifest V3 and removing it, I'm still perplexed why BCNY chooses Blink/Chromium as their base for both Arc and Dia. Since they were Mac-first, it would make more sense to choose Webkit and it would play nicer with battery life.
Additionally, a Webkit-based browser on Windows would be a breath of fresh air for the virtual-monopoly that is Chromium/Blink.
