It does sound similar, unfortunately the limited response doesn't seem
to address the issue in that we are doing it in a way that nobody (or at
least commonly) else does.
To me this sounds strikingly familiar to how we ignored how everyone
else handled commenting out parameters vs how we thought we were right
until we finally decided everyone else was already correct and changed
it. (metaphorically speaking)
That said, I am not interested in a philosophical argument. It appears
to me that based on the referenced PDF that we are wrong. How do we fix
it? What are the implications of that? I just want to solve the problem.
Sincerely,
JD
