I agree, some types are rarely used now. Then maybe it should be removed?
There are other rarely used types. Example:
$ awk '/^mml,/||/^jad,/||/^wml,/||/^jar,/||/^war,/||/^ear,/||/^hqx,/|| \
       /^odg,/||/^odp,/||/^ods,/||/^odt,/||/^wmlc,/||/^wasm,/||/^cco,/|| \
       /^jardiff,/||/^jnlp,/||/^sea,/||/^sit,/||/^xpi,/||/^xspf,/|| \
       /^ra,/||/^3gp,/||/^asf,/' ~/httparchive_exts.csv
3gp,35,75
wml,11,63
odt,16,23
jar,5,12
wasm,5,9
sea,2,8
xspf,4,7
asf,4,6
odg,2,3
ra,3,3
war,1,1
jnlp,1,1
cco,1,1
hqx,1,1
ods,1,1

Maybe then just add the text/tab-separated-values type for .tsv files?

$ awk '/^tsv,/' httparchive_exts.csv
tsv,174,326

Forgot to delete video/x-m4v.

If there were any problems, then Apache would not have added
the `audio/mp4` type for .m4a and mp4a files.

Apache also has such an extension, I think it's worth adding.
I can fix the patch later.

$ awk '/video\/quicktime/' mime.types
video/quicktime                                 qt mov

According to this recommendation:
https://learn.microsoft.com/en-us/windows/win32/wmformat/file-name-extension-guidelines
asf files should not store audio and video streams.
This format is also rarely used, can it be removed as well?
This also applies to the .wmv extension. Then there will be
no need to add the .wma extension.

There are no specific reasons
