Data from (confirmed by) mdn-bcd-collector:

• Chrome ≤15
• Edge 12 / 79
• Firefox ≤4
• Firefox Android ≤86
• IE 10
• Opera ≤12.1 / 15
• Safari 6
• Safari iOS ≤10.3

Chrome ≤15 is assumed to be 5 in most cases where it was 5 here:
#7197

Firefox ≤4 is assumed to be 3 based on:
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/3

Mirrored data:

• Firefox Android 4
• Opera Android ≤12.1 / 14
• Safari iOS 6
• Samsung Internet 1.0
• WebView Android ≤37

Most of the data is very regular. Notable exceptions:

• SVGFEConvolveMatrixElement entries are assumed to have shipped in
  Chrome 6, like api.SVGFEConvolveMatrixElement and its subfeatures.

• SVGFEDropShadowElement was shipped in Chrome 13 / Firefox 30, and
  seemingly never supported in IE, EdgeHTML or Presto.

• In Firefox, something strange happened with 3 of the interfaces. In
  Firefox 21, almost all subfeatures of these tests pass:
  http://mdn-bcd-collector.appspot.com/tests/api/SVGFEComponentTransferElement
  http://mdn-bcd-collector.appspot.com/tests/api/SVGFEFloodElement
  http://mdn-bcd-collector.appspot.com/tests/api/SVGFEGaussianBlurElement (except edgeMode)

  In Firefox 22, the height/result/width/x/y fail. They're back in Firefox
  29/35. This looks like a mishap, but is captured in the data anyway.

Thanks, this is quite impressive. Maybe the largest PR that submits complete real data? (no true or null in here, so great!)

I trust the BCD collector and the mirroring makes sense to me, too. Thanks for also getting into some of the exceptions.

The only change request I have is to please add mdn_urls to the main interfaces at least. The sub features will all be 404, so let's not add these, but I think all the interfaces are present on MDN.

[foolip]

Do you mean that I should add __compat entries with just mdn_url in them? Wouldn't that be in the merged data anyway?

[Elchi3]

Oh wait, I'm stupid. The interfaces have their mdn_urls anyways already. This is mixins! Nevermind! 😊

Thanks for review @Elchi3!
