That's still a huge amount of information that has to be passed
from the compiler to the linker (to enable it to do full call
graph analysis) I don't see it as practical to mandate this.

After all, the GNAT approach just corresponds to good
programming practice (clearly calling something from a package
at elaboration time without using Elaborate_All is plain bad
coding practice!)

In practice, I don't think anyone has found the static scheme
a big burden except in Ada 83 legacy code. We don't know of
anyone using the dynamic approach *except* in the Ada 83 legacy
code case.
