I think this pattern is close the culture of C/C++, in the sense 
that many like to get a clear view of how their code is related 
to machine code instructions and memory layout. C/C++ is as close 
they feel they can get to machine code without taking the costs 
of dropping down to that level.

Rust and D have some of these, but also a large segment of users 
that are attracted to primarily high level programming. To a 
large extent I think this is a result of how these languages 
present them to newbies. If you present a high level layer to 
newbies you will grow a different user-base profile/culture. I am 
not sure if this is a good move as it is difficult to collect 
feedback that gives a clear focus on where to improve if the 
interests are diverse.

Maybe Zig is doing better than some competitors because it does 
not try to provide a high level experience (or do they?). Anyway, 
from a distance it looks like Zig is attracting a more more 
cohesive group of programmers with more overlapping expectations.
