Every major library management system uses MARC in one way or another.
One could see MARC as the shapefile of libraries ;) The geo data are
mostly related to the cataloguing of modern / historical maps, atlases
and places related to published manuscripts. But you're right, the
format is rather known only among librarians.

If the functions would somehow add any value to the project, I could
prepare a pull request. I would, of course, be willing to maintain the
functions.
