I'm in favour of the addition if it's only used in these special cases you 
mention, where we want to send *all* urls with a given scheme to an 
application, so this indeed *replaces* any mimetype-based lookup.

This is orthogonal to the use cases like "we have a HTTP URL pointing to an 
image, we need an application which supports image/png -and- which supports 
HTTP" - this is another unresolved issue (in KDE we started using X-KDE-
Protocols for that, but let's talk about that in another thread, to not mix up 
the issues). In that case both criterias must be met, so x-scheme-handler/http 
would not work if it's just another mimetype, this is why I'm clearly 
separating the two issues.

But to come back to your use case, all urls with a given scheme, no mimetype 
at all, then OK. I just hope nobody installs a desktop file with x-scheme-
handler/http ever...
