You are right that the first change is present in the current version as far as I can tell now. I figured differently and have no idea why. However, with regard to the second change:

To me this looks equivalent to the issue-4681 version of the

And apparently it isn't suspicious to you that the version is is now identical to the version before applying issue-4681?

The second difference is that the
Philomelos version returns None if voice_id is undefined, the same as
returning voice_id. Note that voice_id is initialized to None as a
result of the first change above.

Well, that's the whole point of the change, isn't it? Not overwriting any previously established voice_id attribute in case get_maybe_exist_named_child call doesn't find one. Yes, the initial value of voice_id is None. But it can be set to other values elsewhere, namely in the next change which is copied.

assuming the regression tests would expose an error if there was one,

How do you figure that when the regression tests passed prior to issue-4681 and the issue does not change the regression tests? Yes, it would have been an excellent idea to change the regression tests in order to ensure that the changed behavior is not silently reverted at a later time. Since this obviously did not happen, the regtests don't help for this item.

The third change is present, but the omission of the second change will, if I understand this correctly, cause its effects to be overwritten.

The fourth change, as you noticed, is absent. I haven't analyzed it in detail, just noticed its absence. You haven't analyzed it in detail either but state that the regtests (which unfortunately have not been adapted as a consequence of issue-4681 however) should have caught it.

The fifth change I felt unable to judge. Your analysis might well be accurate. So basically I have to adjust my number from 3 out of 5 missing changes down to 2. We disagree on the effects of the first of those changes, and the only rationale for having the second change removed is that the regtests did not complain. But they don't catch a regression of issue-4681. And I doubt that the change was purely cosmetical.
