I don't understand where in my post I implied that you are on the 
anti GC train.
You brought up the discord thing to make a point that GC's have 
bottlenecks and allocators are the solution?
However, their solution to a GC bottleneck was not to fix it by 
using allocators but to dump their Go code in favor of a Rust 
port.
Neither can I see a connection of Go's GC's bottleneck to D's nor 
how allocators would fix it.
Go's GC would still run a collection every 2 minutes.
So you would either need a GC.disable to stop it from collecting 
where you can't suffer the impact, with a GC.collect to run it 
when it suits you, or you would need to completely disable the GC.
Or you port your entire code base to a non-GC language.

Maybe because the GC has no disadvantage to them. But that's my 
own guess.
If you absolutely can't suffer a GC, there's -betterC, in case 
you didn't know.

I guess it's an ignorant point of view, but I don't see how 
someone whose constraints for writing high-performance, and/or 
real-time, and/or embedded/micro-architecture code, which 
prohibits the use of a GC, would find D-Runtime/Phobos meeting 
their requirements.
There's at least one lightweight implementation of D-Runtime.
And Phobos? Everything that allocates or is templated will likely 
be too slow/bloated in that case, thus a specialized solution 
that takes advantage of context seems to be necessary.
