Hi Eric -
I think one helpful guide for you would be this recent post by Davide (dcaratti@redhat.com on the cc list):
https://developers.redhat.com/blog/2020/08/19/multipath-tcp-on-red-hat-enterprise-linux-8-3-from-0-to-1-subflows/
With curl, what you're seeing is that existing programs do continue to use regular TCP. The blog post has a section on one approach to making unmodified programs open sockets with IPPROTO_MPTCP.
The MPTCP upstream community has a mailing list at mptcp@lists.01.org and a wiki at https://github.com/multipath-tcp/mptcp_net-next/wiki - and we are working on more documentation with the kind of pointers you're looking for.
Thanks for trying out MPTCP!
