The final render step is also necessary if the user canceled the preview
creation and choose OK. I close the bug as WONTFIX.

You are right, and not.

yes the preview is computed against the whole image IF you don't zoom inside.

When you zoom , the preview render only the visible region on the canvas.

In this case, the final render must be computed over whole image at end.

Note : zooming is important to show effects applied on image details. Don't
forget also the type of preview generated where only one portion of image will
be used.

So, you proposal to not re-compute effect on whole image is only valid if whole
image is show on screen, without a specific image portion to render.
Using 100% of image to preview effect with this kind of tool is typically never
used in production (sharpening, noise reduction, etc...)
