Nah, the engineering standards like that generally make everyone's job easier; the "pro" carpenter will save just as much time as the newbie, hell maybe more.

Design patents are more of "you need to build house with this exact room layout" than "the materials and ways to put them together are standarized"

There's a strong element of that, but there's more to it. It is to the advantage of management that even their experienced developers all speak the same design language, if only because this makes any individual developer easier to replace. Corps don't want a situation where the whole company is hanging off one brilliant programmer's completely impenetrable code. TempleOS is awesome, but not for businesses.
