As you stated, the fact that there is an extensive review system with high participation, that this alone organically leads to particular trends in sw design. I will have to read more about ‘specs', as I don’t quite get what they are and how they are different from blueprints.

It sounds to me like much is built into 1) the detailed system of reviews, 2) an informal hierarchy of wise technicians, and now 3) modularization efforts like this Oslo. Did I summarize this adequately?

Agreed, it's why also a ARB (or something with a different name) might
be useful in the future somehow... Not saying I like more
process/red-tape but yes many of us have lamented and I'm not sure of a
better way to stop lamenting. Such a ARB (architecture review board)
could at least start off being a ADB (architecture documenting board?)
and fill in the gaps in documentation/understanding of what the
(shared?) architectures actually are (with the help of PTLs I hope).
Do note I tried to use as many 3 letter acronyms as I could, ha.
