I tried to find a more recent discussion but search found this:
https://lists.gnu.org/archive/html/emacs-devel/2010-05/msg00458.html

But fortunately now we have window-states that are better suitable to build
the feature that you are adding.  So if you will have such template based
on exported window-state layout:

(hc (vc (leaf (buffer "\\`\\*\\(locals\\|registers\\) of .*\\*\\'"))
        (leaf (buffer "\\`\\*\\(breakpoints\\|threads\\) of .*\\*\\'")))
    (vc (leaf (buffer "\\`\\*memory of .*\\*\\'"))
        (leaf (buffer "\\`\\*stack frames of .*\\*\\'"))))

(window-sizes are omitted in this example, but they could be expressed
as percentage of relative window dimensions)

then calling (display-buffer "*memory of emacs*") could search in
such window-tree, find a window that matches the buffer name and
display this buffer in it.

This could be implemented by just adding a new display-buffer action.
