I think Karl may have expected that fonts could be developed in such a
way that combining diacritical marks would be spaced properly above the
base character, more or less by magic. I used to think that would be
possible when I knew nothing about font design, instead of knowing
almost nothing about font design as I do now.
I still think it would be reasonable to expect combining marks like
macrons and circumflexes to be always centered over the base character,
not off to the right, even if the vertical spacing is wrong. Like I
said, almost nothing.
