I don't know whether it is reasonable, but it is a departure of the current use.

The docstring of `defvar' clearly says:

"Define symbol as a variable, and return symbol.
You are not required to define a variable in order to use it,
but the definition can supply documentation and an initial value
in a way that tags can recognize."

Getting a warning is tantamount to be required to define it...

Now, I'm all for lexically scoped Lisp and (declare (special
mydynamic-var)) and the like, but clearly that's not the route elisp
is following.
