And how'd we revert to a valid state? Using `set-window-configuration'?
Wasn't that something you wanted to avoid?

For modeline dragging we need a function which resizes a window by
moving _one edge_ only (which can be either the leading or the trailing
one). If, in addition, we want to call that function recursively we
must be able to specify _which edge_ it should move, that is, it must be
able to move trailing _and_ leading edges. Moreover, we probably want
to specify whether the function is allowed to delete windows, resize
windows below `window-min-height' or `window-min-width', or ignore the
value of `window-size-fixed'.
Also I think that a call with N > 1 failing to resize the window should
be able to result in an abort. An application that can't get a window
of the appropriate size might prefer to use a new frame and leave the
original configuration unchanged. Should it do that by saving the
window configuration and restoring it provided the amount returned by
`window-resize' doesn't fit its needs?

Including siblings of the window's parent, grandparent, ... I suppose.

IMO `window-resize' should be written in Elisp while the check whether a
window tree is invalid would reside in C to guarantee that Elisp code
never crashes Emacs. I'm not sure about the interface though. I
imagine primitives like say `book-window-parent', `book-window-top',
`book-window-lines', ... and have a function checking-in the booked
values by (1) checking whether the booked values form a valid window
tree and, if that is the case, (2) replacing the actual values by the
booked values.
