Thanks a lot for bringing this up. As Jérémie pointed out, here is the issue for this:


Please give it a thumbs up if you like it. If you want to help get this into the standard, we need somebody to take a lead on this proposal. One must organize and lead the conversation in the issue to get an agreement on the best path forward, and then have a proposal ready for the next committee meeting (in February) that addresses the committee and community's comments. Please let me know if you'd be willing to do that, that would be a huge help.

The committee will then consider it and provide feedback.
