I removed the setting as requested.

My understanding is that the FTM is set when a feature is complete. This PR completes comparisons for the reference wrapper, which is the first part of the paper. So it the FTM should(could) be set. 
The paper has a second (to me unrelated) part about constraining the equality of unrelated to reference wrapper types. For that part the paper defines a second FTM `__cpp_lib_constrained_equality`.
This is how I understand it. Is my thinking wrong?
