window.el.  This way you can avoid all limitations.

display-buffer-at-bottom looks adequate for its purpose. I'm only pointing out that *completions* is very rarely _below_ where you are.

I don't want to write my own action because it'll just be another piece of logic behaving differently from the rest. Hardly a beneficial thing.

Why can't you increase the window height?

If we're emulating an IDE, though, the standard is to default to ~30% of the frame height, or less. The user might change the height, but even so, they're unlikely to increase it above 50% of the frame height, and in doing that, they'll cut the height of all file-visiting windows by half.
