100% correct.

Too hackish to my taste. Everyone writing a text viewer/editor
will not think of adding that line.

What other options do we have? We could check if the current part supports
text/plain, when trying to open something for text/html - if it does, it's not
"good enough", it's a source viewer. Still hackish, but at least can all be done
inside of Konqueror.

The option to "always switch back to the preferred viewer for a given mimetype"
is more generic, but doesn't sound too good to me, it prevents reusing the same
handler that's not the preferred one..... Thinking of e.g. an image viewer it would
be an unexpected behaviour.
