Is there a difference between rlang::set_names and dplyr::rename_with? Are both needed?

library(purrr)
iris %>%
  set_names( . %>% sub("Petal", "x", .) %>% sub("Sepal", "y", .)) %>%
  names
## [1] "y.Length" "y.Width"  "x.Length" "x.Width"  "Species" 

# same code except set_names replaced with rename_with
library(dplyr)
iris %>%
  rename_with( . %>% sub("Petal", "x", .) %>% sub("Sepal", "y", .)) %>%
  names
## [1] "y.Length" "y.Width"  "x.Length" "x.Width"  "Species"
