The automatic paging is only for printing to standard output and it doesn't meddle with this functionality. By the way, zsh built-in pager (invoked with `<`) has this behavior. It prints output to display but it pipes it to an actual pager if size is large.

Having written a Rust wc implementation a few years ago (https://github.com/Freaky/cw), I had a look at theirs. It's pretty naive - a simple linewise read_until loop, a conditional to avoid word splitting and such if it's not needed, and for some reason it collects results into an array and prints when it's done rather than printing as it goes. It doesn't support --files0-from like GNU wc, so isn't a drop-in replacement from that perspective. It also has the sadly common Rust trope of only supporting filenames that are valid UTF-8. It doesn't seem overly slow considering its simplicity - usually trading blows with GNU and BSD wc. Perhaps the most glaring omission is the lack of a fast path for -c, which should reduce to a stat() call. Also unfortunate not to use the excellent bytecount crate to provide a very fast -l/m path.
