Re-add Feature-Policy header as an alias? #430

Open gsnedders opened 2 years ago

Given the rename of the Feature-Policy HTTP header to Permissions-Policy, despite existing usage, is anyone currently expecting to this that change any time soon? The changed happened 18 months ago, and AFAICT nobody has as much as shipped it as an alias? Do we realistically expect those already shipping it (currently just Chromium and derivatives) to drop support for Feature-Policy, or should it be re-added to the spec as an alias?

They have a different syntax and require a different parser. I'd prefer not having to support Feature-Policy.
