&gt; I guess that depends on how you define debate. I&#x27;m referring to that the proposal is made and some people show their distaste for part of what is proposed. Those that made the proposal respond. I see no resistance to the feature being introduced in that, just disagreement on a part of the proposal.<p>Just to be clear, neither I nor Addy Osmani proposed CSS Custom Properties. We&#x27;re just excited about the feature and sharing it with others. So when people respond negatively to us, it doesn&#x27;t feel like debating.<p>The time for debating was when it was being discussed in the working group; before it was implemented in three different browsers.
