Review Comment:
   Maybe using 
[`purrr::imap()`](https://purrr.tidyverse.org/reference/imap.html) here will 
make the lint warning go away? I don't see how this current version is more 
complex than what is currently on master.
   
   ```suggestion
           .data$aggregations <- imap(.data$aggregations, function(x, name) {
             # Embed the name inside the aggregation objects
             # `target` and `name` are the same because we Project the data 
that way
             x[["name"]] <- x[["target"]] <- name
             x
           })
   ```
