"which included several names that you removed after some months."

I removed information based on lack of verifiability as I have mentioned in my changeset comments. I have always been very lenient in Antartica as the data sources are difficult to come by, but I have seen many really bad edits all over it, including mappers using it as a scratchpad and leaving junk behind. So, in order to maintain data reliability, if you can provide a source, I will readd those names or features after verifying them and also add the source to the wiki: https://wiki.openstreetmap.org/wiki/Antarctica/Data_Sources

"We had to correct an unclassified road into Mount Vinson from you."

I don't fully agree with the correction, but none of us have access to data that demonstrates which mapping is more correct, we only have the Strava running heatmaps, where many tracklogs match motorised routes elsewhere in Antarctica, so I think it is not worth discussing this case without better data.

"And even the Svalbard example that you are citing, they are using a secondary (wrongly) to join two sectors of the same urban settlement. But as soon as the roads leave the Village they become unclassified roads."

Using highway=secondary to connect place=suburb is generally correct as far as I know if we don't assume any country's specific highway classification scheme. Ways that continue into sparser areas past a settlement's core have lower classification in Svalbard as they did in the Fildes Peninsula before these recent edits, so the pattern was essentially the same.

"Then again, please join the Chilean community."

Thank you, I will look into that. But as Antarctica is international space under the Antarctic Treaty, I think any discussion on it should involve communities from multiple countries, be it in Fildes, McMurdo or other areas. Since each local community has its own ideas about highway classification, disagreements are inevitable and it's best to find consensus rather than impose any country's specific system. While the Chilean settlement in the Fildes Peninsula is the largest and oldest, the peninsula is also home to year-round Russian, Chinese and Uruguayan stations.

"The eastern part, which starts as primary (wrongly), then leaves town as a tertiary just to head to a radar and the OREO Doomsday Vault. That is wrong too."

I think it would generally make sense for this route to be highway=tertiary up to the entrance of the Camp Beretz settlement (currently not mapped in OSM) and also all the way up to the Gruve 7 coal mine which likely attracts heavy traffic.
