Conceptual it should not be hard for MPTCP to deal with this issue.
In practice, we may have a bit of deployment problem. 

But the bigger question would be, if MPTCP would iterate over all possible
sources addresses in a happy-eyeball fashion, is that something we want?
We already have the issue that HE masks brokenness. If we promote that 
as a default mode in transport protocols, we may invite quite a big mess.
