This PR would largely fix the opEquals problem (though it doesn't deal with
actually removing opEquals from Object, just making it so that you don't
need it):

https://github.com/dlang/druntime/pull/1439

However, it's just languished (probably because it's in druntime and not
terribly interesting). But actually removing opEquals and replacing the
others gets a lot more interesting (e.g. we have to finishing templatizing
the built-in AAs as one of the steps), so as critical as that PR is, it's
only one small step.
