tk...@chromium.org Specification:
None; This is a straight-forward extension of an existing feature Any focusable HTML or SVG element supports 'autofocus' attribute. 'Autofocus' has been supported for a limited number of HTML elements, and there are elements which could be focusable but don't support 'autofocus' attribute. This feature resolves this inconsistent situation.

For example, autofocus attribute doesn't work for <div contenteditable=true> for now.
Low interoperability risk.  Apple and Mozilla are positive.

Low compatibility risk.
This feature moves 'autofocus' IDL attribute from some HTMLElement sub-interfaces to HTMLOrSVGElement.  The code like
  Object.getOwnPropertyDescriptor(HTMLInputElement.prototype, 'autofocus')
doesn't return a descriptor after the change.  We guess such code is used very rarely.

Tests will be merged soon; https://github.com/web-platform-tests/wpt/pull/18558 https://bugs.chromium.org/p/chromium/issues/detail?id=995679 https://chromestatus.com/feature/5654905853313024

Also code like -
typeof element.autofocus !== "undefined"
Which might be used to detect an input, perhaps, would return different results.
But I am not worried much, but it is worth a quick search.

I see it also works with tabindex. Cool!

Note that the plan is to name it HTMLOrForeignElement instead of HTMLOrSVGElement to include things like MathML, relevant info is here:

LGTM1

Seems like a useful change and I agree that while it's observable, it's not very likely to result in actual breakage.

I'm not sure this counts as "public support" since it's not on Mozilla's standard-positions repo. At the same time, it's definitely an encouraging signal.

Edge: No public signals Safari: Public support (https://github.com/whatwg/html/issues/833#issuecomment-432993680) Web developers: No signals
