Actually, it's -W; and since changeword will eventually be dropped if m4
2.0 is ever released, no one is relying on it.

In earlier versions of m4, 'm4 -e' did what 'm4 -i' does in other
implementations (namely, trigger an interactive run where signals and
buffering are changed).  But we have been issuing a deprecation warning
for that since 1.4.7, so it may be worth reusing such a short option in
the future.  In the meantime, I would not be opposed to the idea via a
long option, as it definitely sounds useful.
