Interesting.  The fun fact is that it won't work anyway, since 
MIME types as checked by EDK II HTTP Boot driver are misspelled, 
notably it checks for "application/vnd.efi-img" (note "efi-img" 
instead of "efi.img") and "application/vnd.efi-iso" (the same).

For reference, as of current master:

https://github.com/tianocore/edk2/blob/b7f8779/NetworkPkg/HttpBootDxe/HttpBootDxe.h#L79
https://github.com/tianocore/edk2/blob/b7f8779/NetworkPkg/HttpBootDxe/HttpBootSupport.c#L661

Note well that if the MIME type is not matched, extension-based 
matching is used (wiki page linked says "if "Content-Type" header 
is not present", which is a quite different behaviour).  Given the 
wrong MIME types in matching, extension-based matching is the only 
code path which works in practice, and any MIME type, including 
"application/binary", is expected to work well.

Dropped for now, thanks.

Sure, as discussed previously, HTTP Archive data is mostly focused 
on how sites are built, and not on various files available for 
download 
(https://freenginx.org/pipermail/nginx-devel/2024-March/000099.html).  
Other sources to demonstrate significance of particular extensions 
are welcome.

(Also, Theora support seems to be removed from browsers, see 
https://www.phoronix.com/news/Mozilla-Eyes-Dropping-Theora.)

Dropped, thanks for trying.

Both m4a and m4v use the same container format as mp4, but they 
are not mp4.  Some of the files might be compatible with mp4, but 
that's not something guaranteed.  As such, using audio/mp4 and 
video/mp4 types for them is questionable.  Hence the question 
about reasons.

I don't think it is a good idea to add types unless there 
practical requests.
