That's great, but only if your implementation isn't hacky, non-portable and
full of UB. It might show that the data is present so that they can implement
it, but there are other ways of showing the data is present than to use it in
hacky ways.

In my opinion, you're losing time focusing on what's not important. And you're
losing the reader's attention with unnecessary details, which then they will
proceed to critique. That's a disservice.

Something about "forest" and "trees" comes to mind.
