<table wicket:id="table" rowsperpage="10"> <== what if you move this component somewhere where rowsperpage="20" - shouldnt that update?
now thats a simple example, and a pull model can help
what if now based on different attributes you create different hierarchies of child components. then you need to recreate those hierarchies when your component is moved - and that might be a lot of work. so things will seriously break if you do not handle that properly.
i dont think moving components will be a very likely usecase to start with, but we need to have good support for it nonetheless.i would rather have a more explicit error/api and thats why i proposed the extra interface.

So which features are they then? Anything else other than the ability
to read markup (attributes)?
And why/ when does the markup that the component is attached to
switch? Isn't this only the case when e.g. the parent depends on
markup of a child? And is it always the component itself we want to
protect, or is it the parent?

Well, the 'propably breaking thing' is where we don't agree on, as I
think it's not a common case at all (or read will be if you like). And
even if a component got initialized using some attribute of the markup
it's attached to and that markup changes somehow (though I don't see
how this happens by switching the parent), even that doesn't mean it
is suddenly in an illegal state. Only if the component developer
decides to, which he can by rechecking attributes e.g. when rendering.
