Illustrator 26.3.1 unable to export SWF files means and more

So the new version can't export SWF files anymore... that function was great for me as I used the SWF files simply as a preview of short frame by frame animations. I understand that Flash will die but can't we have an option to see a preview of the "animated layers"? Illustrator is actually very good to draw frame by frame animations and it's a shame we can't preview them anymore to correct movements and other things.

Furthermore it would be great to have an option to export all layers into PNG or JPG... I don't understand how's that still not a thing...
