Actually, it would be really nice to continue the discussion in that thread.
You don't need the forum for that.  Just write to nginx-devel mailing list:

The reason why it died is we got no feedback from users showing the patches
worked for them.  A few people showed interest, but eventually sent no
feedback.

I've updated the series.  Not it applies to the latest nginx source code.

The best way to make sure the feature is supported is to commit the patches.
As I said before, we need more feedback for that.  Until then we'll try to keep
the patches up-to-date.  But this may become harder as the source code changes.

We'll be happy to get feedback from you.
