but nothing shipped yet by their mirrors, unlike debian.
This adds Ondřej Surý's PPA to your system so you can upgrade the packages.
Most of docker is like this. Images provided by volunteers, and not related to the project. Using docker images you don't maintain yourself, and at least don't upgrade yourself, is not the best recipe for security.

Honestly I don't even understand why so many docker images prefer to build software from sources, rather than just installing them from debian repositories.
Because Debian uses older relases and a lot of custom patches. One example: Nodejs still doesn't have Typescript support in the Debian packages.
Distribution packages vs. official build from source has both pros and cons.
