We can continue to move it forward along the recommendation track or we can "end-of-life" it by publishing it as a Note. In light of the src-n proposal, I'm inclined for us to publish it as a Note. The rationale being that src-n does exactly the same things that <picture> was doing, but overcomes the shortcomings with <picture>, in particular:

Hi,

I personally think <picture> still is the way more intuitive markup for normal developers. 
Some people might remember the approach I proposed 2.5 years ago to the whatwg - it was quite similar to srcN but was rejected by RICG and not followed along by WHATWG either as it has some caveats:

- not easy to understand
- harder to maintain due to the {n} number, like removing number 2 out 3

This said, your points on the complexity of implementation are all true.
I hope all of you are aware that this srcN or whatever solution we come up are a milestone and will hold for at least several years.
I simply want to avoid that all developers will complain about this in one year and have to deal with a syntax that people simply don't understand.

And I also think we already created a big mess due to the implementation and adoption by developers of srcset which now should be replaced by srcN.
Sorry, this might sound a bit harsh but many people don't care about a standard solution of respimg anymore because of all that confusion. And I could
imagine that WebKit might be more cautious to implement such new things in future.

My 2 cents on the topic. Thanks for considering it.

Cheers,
-Anselm
