Question of intent: stash push --include-untracked

I'm a bit perplexed about what is intended follow a git stash push --include-untracked. Suppose I have files a,b,c,known modified, but only known is in the index. After the stash, stash show only displays known. A subsequent pop will restore a,b,c. So functionally push and pop are fine, but show appears to ignores files in the stash. The log shows a previous commit (dce2e3e) to the WIP stash (ab0834c) that does contain the untracked files, and git diff is happy to show the contents when using the ref directly. It is just counterintuitive for stash show not to display all entries previously pushed. I would have expected symmetry. Is this new, or intended.

*-.   ab0834c (refs/stash) WIP on master: bf223fc Updated known

This on git 2.23.0
