What's the benefit of promises like this here?

Just spin up a loop of 50 call chains. When one completes you just do the next on next tick. It's like 3 lines of code. No libraries needed. Then you're always doing 50 at a time. You can still use await.

async work() { await thing(); nextTick(work); }

for(to 50) { work(); }

then maybe a separate timer to check how many tasks are active I guess.

Promise.all waits for all 50 promises to resolve, so if one of these promises takes 3s, while the other 49 are taking 0.5s, you're waisting 2.5s awaiting each batch.

The implementation is rather simple, but more than 3 LoC: https://github.com/whilenot-dev/promises-batched/blob/main/s...

I know. My point is you can do better without a library.

Why not write all of our applications on one file? Why bother using (language specific) modules? To take your argument to the logical extreme, DRY is a fanatical doomsday computer science cult.
