In my experimentation it seemed that sometimes Xcode created a blank
line in the editor space for the bubble. Maybe I was wrong.

Finding/tuning a good behaviour is not necessarily "simple".

Well, *I* like to be able to skim the list of errors first to get an
idea of what was broken. Things can be more complicated, for example,
when autogenerated code is involved, and you sometimes need to get the
big picture to see what's happened.
Xcode does not keep the error list for "diagnostic purposes". It's
simply in a separate window, which is Xcode's closest equivalent to a
pad. Users may not choose to use it most of the time, and that's fine,
but there will always be circumstances when it's useful.

That doesn't work. Breakpoints are rendered across the full line, not
just in the margin.

Yes to which question? The latter?

You have yet to explain why we should "kill" it. Xcode still has one
for a reason.
If we get this right, we will make users happier. If we are too
disruptive without considering the consequences, we will lose users.
Don't forget that users come from different perspectives, and emacs
and Xcode users like yourself are a tiny minority compared to those
who are familiar with other IDEs, especially VS. Blithely dismissing
these other viewpoints is incredibly counterproductive. We should be
discussing how we can make it more usable for everyone.
