John, understood, and thank you! I will make a note to check back on the site regularly to see if CSD moves into "Under Consideration", etc.

If anyone can comment for Microsoft Edge, it would be appreciated.

Hi John, good to hear from you and thanks - I knew those weren't the right places and appreciate you sharing the canonical source!

Are you aware of any plans for Webkit to support Clear-Site-Data in the future?

We typically don’t comment on future plans. But the WebKit Status page will say “Under Consideration,” “In Development,“ “Supported In Preview,” and “Supported” accordingly. In rare cases, an engineer might have started development without bumping the feature’s status yet.

   Regards, John

WebKit does not support Clear-Site-Data as of now.

Would particularly appreciate any info from the Safari and Edge folks on the list here.

Much appreciated,
