Re: Extending Class Proposal

Hi, I haven't heard back from anyone on this, so I wanted to follow up.

I hope the lack of response is because of busyness and not due to a lack of
interest in the topic/proposal. I think the ability to natively extend
classes in CSS would be a huge win.

If any discussion on this topic is happening outside this list, I'd love to
be pointed in that direction.
