It seems to be an unfortunate collision that multiple new packages should be
proposed when Abstract Interfaces still aren't established firmly.
It is highly likely that some packages (for example, Data structures
components) may look significantly better if they can use Abstract Interfaces.
But one can't expect "widely used" prototype interface-based packages for
standartization until Abstract Interfaces went into practice in Ada.
So, perhaps, standartization of packages that can significantly benefit
from Abstract Interfaces should be delayed, and follow the Core standard
after year or two.
