This is fine, you can use the option to ignore directory metadata from
diffoscope output, so that this won't pollute the output.

3 and 2 should be investigated. Do you get these diffs even with grafts
disabled?

Should not be a problem, it shows the diff is too big. You have diffoscope
options to increase that, but as problems are fixed the output should
return to the normal range.
