You seem to be missing my point: I see your change as making it harder and less likely that we will address this during code review, because now it's not even in the same file, it's not going to show up in the diff. Right now, when someone changes an operation by adding an attribute or something like this, I have the doc right above in the same diff and can review it. 

Refactoring common parts of the doc in macros may make sense, but I don't see a strong case for this new file, and there is too many downsides at the moment.
