The WG charter is at: https://datatracker.ietf.org/wg/dnssd/charter/. 
A thing to note is that both large enterprises and (small) homenets are in scope, one of which is managed, one of which isn’t.

The requirements are documented in RFC 7558, which was published last year.

The current hybrid proxy draft is at https://tools.ietf.org/html/draft-ietf-dnssd-hybrid-03, and is likely to be pushed to the IESG after the next update, based on discussion at the BA meeting. 
Section 6 describes the current implementation status. 
The author is Stuart Cheshire, who also of course is an author of mDNS and DNS-SD.

A parallel DNS Push draft allows optimisation, see: https://tools.ietf.org/html/draft-ietf-dnssd-push-07
(This draft is being split into two parts after discussion at the BA meeting, one of which will be done in the dnsop WG)

Finally, Markus has written a homenet-oriented hybrid proxy draft: https://tools.ietf.org/html/draft-ietf-homenet-hybrid-proxy-zeroconf-02, which aims to handle the unmanaged use of hybrid proxy.
