In South Korea, at least 8 popular models of Android smartphones from at 
least two different vendors are shipped to endusers with MPTCP included 
in their kernel even if MPTCP is not yet part of the mainline Linux 
kernel. This deployment is described in
https://www.ietfjournal.org/multipath-tcp-deployments/


In June, when Apple announced that they would allow any app to use MPTCP 
in iOS11, they also mentioned that they would help to push MPTCP 
upstream in the Linux kernel. This will obvisouly require non-trivial 
engineering efforts.
