The presentation seems to be openly addressing "legacy / technical debt".
Referring to an large code base.

The README in, e.g.,  Dependency_Graph_Extractor lists some
contemporary Versions of compiler and tools.

Speculating, an ever more complex and changing language requires
efforts becoming correspondingly more complex and changing.
I understand that recent GNATs have dropped some support for less
recent editions of the Ada language.

Anyway, if Renaissance-Ada extracts information about programs, it adds clarity.
That seems helpful, as it saves time and money - if that's what you
want to achieve.
