The AREA and PERIMETER "items" (fields) in an Arc/Info coverages were maintained by the system, right? Could the user overwrite them?

Question

We have zoning snapshots from pre-2000 that were saved as ArcInfo coverages. Because ArcGIS Pro can't read coverages, we are working on a python script to convert them to file geodatabase feature classes and annotation. Quick question: were the AREA and PERIMETER 'items' (fields) in a polygon attribute table maintained by the ArcInfo software, similarly to how ArcGIS maintains the shape_area and shape_length in geodatabases these days? I think the answer was yes, but it would be good to get some confirmation. Also, could ArcInfo users edit the AREA and PERMITER fields? Again, I think I know the answer: No. But please confirm.

Maybe it was just conventional wisdom to not to edit them.

@VinceAngelo ; You are stuck on a desert island and you can only have one data structure.  Coverage or Shape File: which do you choose?

My (hazy) memory was that they were in the INFO file, and could be edited, but would be clobbered by the next BUILD or CLEAN.
