If you mean "However, if you increase it too far, Emacs could run
out of memory trying to make the stack bigger." make "no hard
limit" clear, I don't agree.  Who will know what the connection
between 'max-specpdl-size' and stack is without reading source
and/or without reading elisp manual?  Perhaps even reading elisp
manual is insufficient.
