Thank you for chiming in in support. I felt surrounded and outnumbered...

Indeed, in my mind having two sides of that "coin" is quite natural... and I

confusion and disagreement on what it stands for.

Unfortunately, I do not feel that comfortable with "compiler firewall"
either as IMO it might be even more susceptible to strict interpretation.
