See

https://salsa.debian.org/apt-team/aptitude/-/commit/34b4a391d41f8c59581662956712c26590d8665a

APT 1.1 replaced per-package pins by per-version pins, but still
caculated the old pins and provided the A{B,P}I to access them,
despite not using them anymore. This has been removed in apt 1.9.

It's not clear what you'd want to show here, given that a pin
applies to a version and not a package these days.
