I do think it would would be nice if pairwise_test_bin could output ResponseStats separately as SampleSizes ResponderN WilsonCIs if needed.

One immediate post-hoc solution courtesy of chatGPT:

parse_bin_SampleSize <- function(ResponseStat_str) {
  result <- sub("^(\\d+)/\\d+.*vs\\.\\s(\\d+)/\\d+.*$", "\\1 vs. \\2", ResponseStat_str)
  return(result)
}
# using the ?pairwise_test_bin example
group_testing$SampleSizes = parse_bin_SampleSize(group_testing$ResponseStats)

Some notes on this enhancement: the backend code is fairly hard coded, see response_info_here_by_group in source code. This may require a little refactor.
