It'd be really nice to unprefix these properties for CSS Grid Layout. This would be similar to what we're already doing for "fit-content" which is unprefix for Grid Layout, but prefixed if you use it in "width" or "height" properties.
After checking the status of things I believe we should unprefix min-content, max-content and fit-content for all the elements and not only Grid Layout. As we're now shipping Grid Layout, having to mix prefixes with no prefixes in declarations is really confusing: grid-tempalte-columns: -webkit-min-content fit-content(500px) -webkit-max-content; So my proposal would be to follow the path started by Blink and unprefix those properties, and wait until for the CSS WG resolution regarding -webkit-fill-available. That would move us to the same status than Blink. See https://bugs.chromium.org/p/chromium/issues/detail?id=245157 for more information. There were a previous discussion on webkit-dev about this, and the only comment was in favor of doing it: https://lists.webkit.org/pipermail/webkit-dev/2015-August/027604.html Also there's a FIXME on the new parser about this: // FIXME-NEWPARSER: Drop the prefix on min-content, max-content and fit-content. Note that we should keep support for the prefixed properties, as people have been using them for a long time. They could eventually be deprecated and removed in the future.

Created attachment 303638 [details] Patch Update results for css3/flexbox/orthogonal-writing-modes-and-intrinsic-sizing.html that was already using the unprefixed version.
Please also update CSSProperties.json.
(In reply to comment #4) > Please also update CSSProperties.json. These are values for width and height properties (also min|max-width|height), so not new properties but new keywords. I don't find the old prefixed versions on CSSProperties.json, what should I add there?
