I'm intrigued to know why? It'd be goods if hooks did everything that
should be expected of them, and from what I'm hearing, I think that
they're a pretty good fit for the problem - perhaps not an exact one,
but that may just mean that they need a little work...

Seems to me that this is why hooks work better - a content-filter, for
example, may know that it has to come before or after certain other
filters, if they are being used. Hooks let you do that.

BTW, an unaddressed problem with hooks is that we don't have a name
registry, and they need unique names. We should fix this.
