how about scaling the sprite 2 times up if it had this problem
or averaging the pixel values inside of the 4 subpixel square

Scaling breaks the size reporter
Averaging breaks colour collision detection
It's impossible to remove this mode (which was since 2.0), like it is impossible to remove the awkward hybrid string/double variable type (which was since the Java player; the offline 1.4 player has an even more awkward type), due to it breaking compatibility.

the scaling issue wouldn't be hard to fix, just half all the set size reporters.

though a compatibility mode for subpixel bitmap is a good idea

I use bitmap for Minecraft skins, and I don't want twice as big exports. Support.

Support! I draw a 16x16 image in the bitmap editor, exported it, and it became a 32x32 image. I imported it into a new project, converted it to vector, resized it and convertd it back to bitmap and the image became blurry! These half pixels don't make any scene and should be removed.
