The primary thrust of that paper is focused on cases where a person
wrote code that uses member function call syntax in good faith that it
would not do ADL gymnastics suddenly having their code exposed to the
vagaries of ADL gymnastics without their will, knowledge, or consent.
The OP's proposal uses an opt-in syntax, so that paper doesn't really
pertain to the OP's proposal. As stated in the proposal, "The syntax
x.f() continues to find only members."
