I saw an old thread that essentially has the same problem with
this one:
12 Jan 2012, Bug: cos ~= cos?

That's because 'simplify' uses 'eval' uses symbol instead of operator.
Not only we don't have the operator version implementation,
we don't have the operator version signature!
We have these symbol version in FunctionSpace, but not operator version.
eval : (%, List SY, List N, List(% -> %)) -> %
eval : (%, List SY, List N, List(List % -> %)) -> %
eval : (%, SY, N, List % -> %) -> %
eval : (%, SY, N, % -> %) -> %
