The original import surveying guidelines actually say to delete the tag
which is likely why it's 95% of the values:
https://wiki.openstreetmap.org/wiki/NaPTAN/Surveying_and_Merging_NaPTAN_and_OSM_data

I only know this because I did a deep dive into those wiki pages back when
I was planning my more recent Aberdeen import.

It's certainly possible to join existing  naptan:AtcoCode  tagged features
to the NaPTAN dataset and apply tags based on that. I originally intended
to update the script I wrote for the import to do exactly that, but never
got round to it. As for the extra tags, there's an old thread on this list
from when I proposed my import where some insightful discussion of the tags
to import took place. In the end I imported less than the original import
because bloating OSM elements with tags from another data set is not
desirable when the identifiers (primary keys) serve as a link. However, I
think your proposed tags are reasonable and more generally applicable to
OSM.
