It's great that it was approved by the editing WG, but we also need wider TAG review for features, and WebKit and Gecko would like to see signals requests go through their official process.

I wasn't sure if we would need TAG to review it after it was approved by representatives from Webkit, Firefox and Chromium so I didn't file a TAG review request. I can certainly do it if it's required.

This not only affects developer ergonomics as now web authors have to attempt to write to the clipboard first in order to find out whether write failed due to a particular mime type not supported by the UAs (or sometimes add version checks that are unreliable at best), but also leads to unnecessary cost in terms of CPU cycles, COGS etc in order to produce an expensive web custom format which may not be supported by a particular browser.

False Tracking bug https://bugs.chromium.org/p/chromium/issues/detail?id=1483026 Measurement Added usage metrics: AsyncClipboardAPISupportsTypes Adoption expectation Excel online is ready to use this API for adding web custom format support. Adoption plan Support for web custom format is already in inner rings, so once this gets added to the clipboard API, Excel would be ready to use it right away.
