Review Comment:
I think the issue is with `list[node, data] <- ...`, which looks off to me.
``` r
list[1, 2] <- "something"
#> Error in list[1, 2] <- "something": object of type 'builtin' is not
subsettable
```
Maybe you want `config <- .config_aggregation(...)` then `node <-
config$node` and `.data <- config$data`?
