Need to have alias field for CSS features

[OnkarRuikar]

For example, the font-stretch property was renamed to font-width. No browser has updated this change. So we have to keep font-stretch page in the docs. Is there any way to reach font-width syntax using font-stretch as input?

Can we add alias property to the CSS features? For example, in this case, add "aliases: ['font-stretch']", to the font-width definition:
