It seems {T68412} (2014) was never applied to production. For example, filearchive in enwiki is:
```
| fa_major_mime | enum('unknown','application','audio','image','text','video','message','model','multipart')
```
While locally it's:
```
fa_major_mime | enum('unknown','application','audio','image','text','video','message','model','multipart','chemical')
```
This has caused massive [[https://people.wikimedia.org/~ladsgroup/by_drift_type_drifts.json|drift reports]]:

I assume wikis created after 2014 wouldn't have this drift. The project for this ({T18491}) is stalled so no rush in fixing this but I hope it gets picked up again. It's a cool project :(
The patches for it can be found in https://gerrit.wikimedia.org/r/c/mediawiki/core/+/135756/13/maintenance/archives/patch-img_major_mime-chemical.sql (and onwards) but I'm not 100% sure it would be work after all these years.
Also another reason why we should avoid using enums ({T119173})
ALTERs needed:
```
ALTER TABLE filearchive CHANGE fa_major_mime fa_major_mime ENUM('unknown','application','audio','image','text','video','message','model','multipart','chemical') default 'unknown';
ALTER TABLE image CHANGE img_major_mime img_major_mime ENUM('unknown','application','audio','image','text','video','message','model','multipart','chemical') default 'unknown';
ALTER TABLE oldimage CHANGE oi_major_mime oi_major_mime ENUM('unknown','application','audio','image','text','video','message','model','multipart','chemical') default 'unknown';
```
