there are roughly 0.082% of software "engineers" that deal with these constraints or have to "think about them"

To be fair most actual engineers just copy paste from a previous project (MEP engineers in architecture) or just look up numbers or equipment in a table (every structural engineer I’ve known). A vanishingly small percentage of any engineer (software or otherwise) are actually doing what most people think as “engineering”.
