But then the name doesn't make it clear that you're splitting an
existing window.  I.e. it's moving towards display-buffer.

Agreed.  Adding a fourth argument to split-window doesn't sound like
a bad solution.

PS: One thing that annoys me in the current working of split-window: it
doesn't let you say which window (the top or the bottom) is the new one.
This was fine back when windows had very little state of their own, but
now it is important when it matters because of window-parameters,
window-dedicated-p, ...
So if we want to improve split-window, I think we should consider this
issue as well.
