Related: I filed a bug with TC39 about Function.prototype.bind.
https://bugs.ecmascript.org/show_bug.cgi?id=1391
Note however that the test in comment 0 doesn't involve bound functions at all; there's clearly a bug regardless of what TC39 decides to do with bound functions.
Summary: Proxies can detect that arrow functions secretly are constructors → Proxies need to understand that arrow functions and most native functions don't have [[Construct]]
