I have to say, I think this issue just needs to be closed out.
The current behavior allows the scene file to specify the viewport, and
the INI file to specify the image size. The aspect ratio is implicit in
the image size. I honestly don't see how any further change is necessary.
Plus, there hasn't been any discussion on this in several years.

Well, you may not, but others do.
The current mechanism is fine as long as the person running the render
is fully aware of the aspect ratio the scene was designed for, or the
final resolution is explicitly specified in an INI file.
The mechanism has its shortcomings however, if the person running the
render is unaware of the intended aspect ratio, and the original author
did not fix the resolution via an INI file.
In an ideal world, I think we would have a means to specify the aspect
ratio in the scene file, and specify only the horizontal or vertical
resolution via INI or command-line parameters, and have the other
dimension computed automatically.

Which is why I like to ask :D

Honestly, I think this is one of those things where expecting the user
to be aware is perfectly reasonable. There are somethings you want to
simplify, but there are times when it's OK to say "You need to be at
least <this> smart to use this product."

Thinking about it more, I think I'd be in agreement with this method.
More precisely, let user specify 2 pieces of information out of width,
height, and aspect ratio for the viewport.
On the rendering end, you could either specify just the width/height
(and use the default for the others from the scene), or you could
specify both width/height to override the scene-specified aspect ratio.
