Not if the version to test is the released one.

Excellent, that is good to know. There is a solution.

Chet explains it clearly.

Just that it is not applied to the present release version 4.4.
Maybe it should be put into a "stack of pending patches" that all will be
applied when a new number release (4.5) has to be done for whatever
other reason.

When that happens, we can say that it "is solved for current release".

I cannot answer for Chet, but please consider this:

In what sense? Other shells don't have this issue and the change got
introduced in 4.3, so, this change is backward compatible with several
versions up to 4.3 (backward compatible).

I am not who must make that call. Someone else must.

If this is not going to be solved in 4.4, then it is a "wontfix" for that
release.

No, it is not "fixed already" on 4.4 release.
Let's call things as they are, not as anyone "hope" they can be.

and the fix is scheduled to go out in the next

Excellent, great, version 5.0 has one issue less to solve. Yay!!

Don't ask me, it is not a call that I can make, I am just a random user.

Yes, there it says that some changes were made to match POSIX
interpretation of $* $@.
I believe that the issue presented in the OP is one of those changes for
5.0.
