Rag, we all understand that you don't write / test code for a living, that much is clear.

Honestly, I would recommend you to keep your speculations and assumptions to yourself, as far as purely technical topics are concerned. All of your arguments, save for the "default option", are kindergarten level, sorry. You don't know how this stuff is done; you think you know, but you don't. This is Dunning-Kruger at its finest.
