Is this going to replace KeywordHintDecoration?

No it won't. The search token is only shown for the default search provider. The
keyword hint decoration will still be used when you're going to do a custom
search.

Looking closer, it looks like this is exactly like the SelectedKeywordDecoration
case, except that you didn't select it, it is implicitly selected, and it draws
things entirely differently and in a different position and stuff.
