You yourself wrote earlier that for fields with the same values ​​there should be the same names:

If tags have the same name, then the meaning should be the same.

Now about rounding. Do the values ​​of these fields look rounded?

F Number: 5.6
AE Aperture: 5.7

[Phil Harvey]

Do the values ​​of these fields look rounded?

Yes.

- Phil

[IWTA]

These values ​​can be said to look rounded:

Exposure Time: 1/800
AE Exposure Time: 1/744

And you can even say for sure that the value 1/744 is rounded to this value - 1/800.
But what value is rounded in case:

F Number: 5.6
AE Aperture: 5.7

Both of these values ​​do not look rounded.


If you leave the tag names "Shutter Speed" and "Aperture" in the "Composite" section unchanged, this will only confuse.
You yourself wrote about this:

If tags have the same name, then the meaning should be the same.

[Phil Harvey]

Nobody has suggested changing these until now, and changing them now could break many scripts/apps that rely on the current behaviour.

- Phil

P.S. Try running the command again with the -n option to avoid any rounding by ExifTool
