The MIME type for both of those would be video/ogg. It wouldn't be hard or
very error-prone to use only the MIME type, Firefox already does that.
It's also not very hard to rely on sniffing, which all the other browsers
do, although Opera still checks the MIME type first.
The only concrete side-effects I can see are:
* Configuring the MIME type is an extra step that seemingly many authors
don't know that they need. That it is easy to configure doesn't really
* Ignoring the MIME type will lead to more videos served as text/plain,
which will render as huge amounts of garbage text in current browsers if
opened directly (i.e. in a top-level browsing context).
