I'm sure abarth will reply with the right thing to do :)

Generally, the Content-Type restriction is to stop confusion in the case where
sites accept uploads of files. If one sniffs the content-type then it might
appear that an extension is from a trusted site when it's actually the case
that the site just let someone random upload the file.

If this is a concern, then we shouldn't accept an extension without the
content-type or, maybe, if we content-sniff then we don't say "xyz.com wishes
to install an extension", but "An unidentified party wishes to install an
extension".

That seems good.
