I'm wondering if Paul's patch at https://debbugs.gnu.org/31995#21 (which
is in Emacs 26.2) effectively fixes this for practical use of undo-tree
history?  That is, we know stack overflow is still possible for a
sufficiently deep nested object, but that patch should make it possible
for Emacs to read much deeper objects without overflowing.
