This package is not outdated. The last version on the project's GitHub
is indeed 4.6.1. [1] There were changes after that, but they were never
tagged as a release. If desired, the -git variant of the package
includes them. [2]
The former maintainer already filed an issue about this. [3] The
upstream repository seems unmaintained, though, with the last commit
from two years ago. I looked around for a more active fork, but no clear
candidate emerged.
Though not in active development, the tools still works. By now, similar
functionality can be achieved also using github-cli. [4] I do not know
if that speaks for or against a deletion. If this package should be
deleted, I would opt to also delete python-grip-git as well as
python-path-and-address and python-path-and-address-git, which only
serve as a dependency for grip.
