Not at all.  In the above example, the error message goes to the
compilation buffer, and it would be weird for that buffer to say "while
loading A while loading B" whereas the compiled code loads neither.

> WHY are you so unconcerned about the debugger case?

In the debugger case, I usually have direct access to the problematic
code and usually don't care that much about the further parts of the
context explaining why that code is executed.
Occasionally I do, but "loading" is not special in this respect: I will
just as often be interested to know which command was used, in which
buffer, or which hook caused that code to be run.

To be honest, I don't see much value in displaying "while loading" in
the echo area in general.  I'm not opposed to it, but the only case
where I know it could be helpful is during compilation (which I'm
mostly interested to see it in the compilation buffer).
