Hm, should we wait here given the renaming?

Hm, should we wait here given the renaming?

I thought about that too — but it seems there’s no need to wait for the renaming, because the spec_url values aren’t going to change as a result of the renaming. That is, when we rename the BCD filenames and the MDN article titles, they’re still going be referencing the same spec URLs.

To be clear: The spec URLs in this patch all already point to the right sections in the relevant specs — and those spec sections have, with one exception, already been retitled to reference the Permissions Policy spec rather than Feature Policy.

So all the spec_url values in this patch already have some form of #permissions-policy anchors — with the one exception being https://w3c.github.io/accelerometer/#accelerometer-interface, because that spec has no Permissions Policy Integration section yet. So I raised w3c/accelerometer#60 to add a Permissions Policy Integration section for that.

But I don’t think we need to block this PR on that PR getting merged first. Instead, after that PR gets merged, we can do a follow-up here to update our spec_url for it.

Well okay, can't hurt to merge this I guess. Thanks for digging into this!
