Based on the last list here:

❯ uv run --python python3.14 --with content-types https://raw.githubusercontent.com/mikeckennedy/content-types/refs/heads/main/samples/compare_to_builtin.py
Compare types in mimetypes vs content-types.
There are 6 types where mimetypes and content-types disagree
mimetypes: .avi video/vnd.avi, content-types: .avi video/x-msvideo
mimetypes: .dll application/octet-stream, content-types: .dll application/x-msdownload
mimetypes: .exe application/octet-stream, content-types: .exe application/x-msdownload
mimetypes: .obj application/octet-stream, content-types: .obj model/obj
mimetypes: .wav audio/vnd.wave, content-types: .wav audio/wav
mimetypes: .xml text/xml, content-types: .xml application/xml

There are 14 types in mimetypes that are not in content-types
.emf : image/emf
.eot : application/vnd.ms-fontobject
.fits: image/fits
.g3  : image/g3fax
.jp2 : image/jp2
.jpm : image/jpm
.jpx : image/jpx
.mk3d: video/matroska-3d
.mka : audio/matroska
.mkv : video/matroska
.ogx : application/ogg
.t38 : image/t38
.tfx : image/tiff-fx
.wmf : image/wmf

There are 14 types in content-types that are not in mimetypes
.7z    -> application/x-7z-compressed
.apk   -> application/vnd.android.package-archive
.deb   -> application/x-debian-package
.glb   -> model/gltf-binary
.gltf  -> model/gltf+json
.gz    -> application/gzip
.m4v   -> video/mp4
.map   -> application/json
.php   -> application/x-httpd-php
.rar   -> application/vnd.rar
.rpm   -> application/x-rpm
.stl   -> model/stl
.tgz   -> application/gzip
.wmv   -> video/x-ms-wmv

I used the MIME types from the following sources.

From https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/MIME_types/Common_types

  • application/x-httpd-php

From Wikipedia:

  • application/vnd.android.package-archive (added to non-strict list because not in IANA or x- prefix)
  • application/x-7z-compressed
  • video/x-m4v

From https://mimetype.io

  • application/x-debian-package
  • application/x-rpm

From https://learn.microsoft.com/en-us/previous-versions/windows/desktop/wmp/file-name-extensions

  • video/x-ms-wmv

All the rest from https://www.iana.org/assignments/media-types/media-types.xhtml

I didn't add these because they're not in IANA or MDN, and I didn't find any authoritative sources:

.map   -> application/json
.tgz   -> application/gzip

Keep this list sorted? It's unclear if the new additions fall under the 'de facto' category or if some of them have standards bodies, like above.

Updated!

It may be clearer to rewrite a bunch of these addition bullets together, even though they were contributed across a few issues. But that can be future copyediting.
