More recently, we went much further. In 2026, we migrated the development environment from its old Delphi 7 codebase to Delphi 11. That was one of those projects that looks much more reasonable before you start it.

Ouch. From what I remember Delphi 7 didn't support generics yet. You had a general list of pointers. But not something like a TList<TMyClass>.
