Change of default search provider is a big thing. You don't change that
often, and there are only few search engines that make sense to be set as
the default one. Browsers can simply ship with predefined set of engines,
and that may be easiest and safest option for users.
There are many many sites that dream they were used as a default search
engine, but their use of this API is only going to annoy or confuse users.
Change of default search engine may have security implications — there are
less tech-savvy people who rely on search engine for *everything* they do
on the net and blindly trust the results (see famous "facebook login"
case). Malicious sites could try to trick people into setting them as
default in order to inject links into (proxied) search results.
There's already <link rel=search> that allows browsers discreetly
integrate site's search in the UI, without having sites clutter layout
with yet another begging button. All the "like-me", "digg-me" & "tweet-me"
buttons are awful enough ;)
