I know Go is justly criticized for many of its design decisions, but it still feels well-designed and "small" to me in day to day usage when many other languages don't.

Eh, the thing with generics coming late is pretty much what I meant by "organically grown".
My best litmus test these days is support for multidimensional arrays because it's always needed at some point in general purpose languages. CL and Ada had it right from the start while C++ needed C++23/26 to get std::mdspan and we still need to wrap it to pass the underlying/owned memory pool around (https://rosettacode.org/wiki/Multi-dimensional_array for more).
Doesn't every language support multidimensional arrays? It's just an array of arrays, no? What am I missing?
An array of arrays is an extremely inefficient and error-prone way to represent multidimensional arrays.
If I want a 1000x1000 array, representing it physically as a single 1000000-element array requires one allocation, and processing it element-by-element (assuming it's stored in the same order we're iterating over it) is sequential in memory and therefore very efficient.
Representing it as 1000 separate 1000-element arrays requires 1000 allocations, and pointer-chasing every time we move from one row to the next.
