LGTM2, can you also please request reviews for the other categories in
chromestatus (and file any relevant issues in the compat spec, if needed)?

Sure, I'm saying that old -webkit-background-clip works with keywords:
border, content, padding. The new one - background-clip works with
border-box, content-box, padding-box.
So, per compat spec -webkit-background-clip should be alias to
background-clip. But since the keywords are different, in order to
handle round trip better (e.g. setting -webkit-background-clip to
content would read back content-box, as it's an alias to
background-clip), we want to drop support of old keywords without -box
for -webkit-background-clip. To see how bad that would we've set up
use counters.
The biggest one is 0.08%. I've manually checked 80% of the websites
reported by that use counter, but found that all of them use *-box
keywords, and only one uses -webkit-background-clip: content.
So I think it's safe to remove support for old keywords.
Hope it's more clear now.

Can you clarify exactly what this means? I'm perfectly fine with
lgtm-ing unprefixing and adding a (temporary?) alias for the old
keyword, but if we start removing support for keywords we need to
be more careful and I want to be sure I understand.

In css-backgrounds-4 also added `border` value, should we
support it when removing the prefix? Maybe this needs to
be discussed further by the CSSWG.

Is there any interest in doing the same for
-webkit-text-fill-color? The two get typically used
in combination for gradient effects:
