#' `r lifecycle::badge("superseded")`

#' [has_tag()] selection helper.
#'
#' @param .data a `linelist` object
#'
#' @param ... the variables to select, using `dplyr` compatible syntax
#'
#' @param tags `r lifecycle::badge("deprecated")` It is now recommended to
#'   leverage the [has_tag()] selection helper rather than this argument.

#' @return The function returns a `linelist` with selected columns.
