Project Oberon, which illustrates that you can create a full interactive OS with rather small amont of code... if you ignore most of the things that we consider essential today, like structs and constants.

Huh? Oberon has both structs and constants.

Sure, Oberon-the-language has structs and constants, but Oberon-the-OS does not not use them consistently. Take a look at this code from memory allocator (from link in my GP comments):

     ELSE GetBlock128(q); SYSTEM.PUT(q+64, 64); SYSTEM.PUT(q+68, -1); SYSTEM.PUT(q+72, list2);

what do you think will happen if someone proposes this code into libc or Linux kernel? What kind of feedback would this receive today?

Good example, I see your point.
