We actually considered this last year, and decided against it. Besides
the argument that it is more expensive - which probably isn't as valid
today due to changes in how we handle those model updates - an
explicit type gives you more flexibility over which converter should
be used.
I'm wondering now whether we should support and/ and in a future
version of Wicket. Andre, if you please add a feature request to our
SF tracker, we'll consider it for Wicket 1.3
