Lars, that was my interpretation as well.

I think the right path forward is for those particularly interested in
multipath to experiment with QUIC extensions inside v1, once the extension
mechanism is defined.  Once some experimentation has happened, we'll be in
a better place to have an informed discussion about some of the points
Christian raised in his multipath requirements draft:
https://tools.ietf.org/html/draft-huitema-quic-mpath-req-01

The recent text being added about Connection Migration should lay some of
the groundwork for adding second paths. https://github.com/
quicwg/base-drafts/pull/1012
